RC Model Manager - User Guide

Welcome to RC Model Manager

This comprehensive guide will help you get the most out of RC Model Manager. Whether you're managing aircraft, tracking maintenance, or organizing your entire RC fleet, we've got you covered.

Getting Started

Installation

Mobile (iOS/Android):

1. Download from App Store (iOS) or Google Play Store (Android)
2. Tap "Install" and wait for download
3. Open the app when installation completes

Desktop (Windows/macOS/Linux):

1. Download the installer for your platform from our website
2. Run the installer
3. Follow on-screen instructions
4. Launch RC Model Manager from your applications

First Launch

When you first open RC Model Manager:

1. Welcome Screen - Brief introduction to the app
2. Profile Creation - Enter your pilot information (optional)
3. Main Screen - You're ready to start!

Creating an Account (Optional but Recommended)

While RC Model Manager works completely offline, creating an account enables:

• ✅ Cloud backup of your data
• ✅ Sync across multiple devices
• ✅ Photo and file synchronization
• ✅ Access from anywhere

Notifications

The bell at the top of the screen tells you when something with a date is coming up or has passed, so you hear about it when you open the app instead of finding out at the field. It's free for everyone.

What It Watches

• Maintenance that's open or in work on your models, transmitters and batteries, whether it's due by date or after a number of flights or sessions, hours or charge cycles
• Certifications about to expire, and Part 107 recurrent training (due 24 months after your last one)
• Club memberships and registrations (FAA, or your operator registration outside the US) about to expire
• Documents, such as insurance policies, about to expire

Retired models, transmitters and batteries are left out.

When Something Shows Up

The bell uses the same Due Soon and Urgent thresholds as the maintenance badges, which you can change in Settings → Maintenance. By default:

• ● Due Soon: within 30 days (or 5 flights, hours or cycles)
• ● Urgent: within 7 days (or 1 flight, hour or cycle)
• ● Overdue / Expired: past its date or limit

When nothing needs attention, the bell is a plain outline. When something does, it fills in and shows how many items there are, in orange or red for the most pressing one.

Using the List

• Tap the bell to see everything, most pressing first, with what it is, what it belongs to and when it's due ("Engine service • Extra 330 • Overdue by 3 days").
• Tap an item to open it: the maintenance task, certification, membership, registration or document. Opening it also marks it as read.

Read or Dismissed

• Mark as read (✉ button): the item stays in the list, under Read, but no longer counts on the bell. Handy for "I know, I'm on it." Use Mark as unread to bring it back to the top.
• Mark all as read (top of the screen): reads everything at once.
• Dismiss (✕, or swipe it away): the item is removed from the list and the bell.

Either way, an item comes back, unread, if it becomes more urgent. Read or dismiss something that's due soon and you won't be bothered again until it turns urgent, then once more if it becomes overdue. You never get the same warning twice, but you'll still hear about it before it's too late.

• Completing a maintenance task, or renewing a certification, membership or registration, removes its item on its own.
• Read and dismissed items are remembered on each device, so reading or dismissing on your phone doesn't change your computer.

Daily Reminder (Optional)

If you'd like to hear about things without opening the app, turn on Settings → Daily Reminder (next to the maintenance thresholds).

• It's off until you turn it on. That's the only time the app asks for permission to send notifications.
• You get at most one notification a day, at the time you choose (9:00 by default), and only on days when something becomes due soon, urgent or overdue. For example: "2 items need attention". On other days you hear nothing.
• Tap the notification to open the list.
• Reminders are worked out on your device from your dates, so they work offline. Maintenance due after a number of flights, hours or cycles only changes when you use the app, so it never triggers a reminder on its own.
• Available on iPhone and iPad, Android, Mac and Windows. Each device has its own setting.
• If you turned notifications off for RC Model Manager in your device's settings, turn them back on there to get the reminder.

Settings & Display

Open Settings and scroll to Appearance to make the app read the way you like. These choices are saved on each device and are not synced, so your phone and your computer can each be set up differently, and two people sharing an account can each have their own.

Language

RC Model Manager is available in English, German, French, Spanish, Italian, Brazilian Portuguese and Japanese.

• By default the app follows your device's language (System default).
• To choose another, tap Language. Each language is listed in its own name, so you can find yours even if the screen is in a language you don't read.
• On Android 13 and later you can also set it in your phone's settings: Apps → RC Model Manager → Language.
• Changing the language never changes your data. Everything you typed stays exactly as you typed it, and devices in different languages sync the same records.

Date Format & 24-Hour Time

• Date Format: the default, Automatic, writes dates the way your language does. Tap it to pick a specific format; each option shows today's date written that way.
• 24-Hour Time: shows times as 14:30 instead of 2:30 PM.
• Decimals follow your language too (for example 3,7 V in German or French), and you can type either a comma or a point.

Thumbnail Size

Choose Small, Medium (the default) or Large photos for the models, transmitters and batteries lists. Small fits more on a phone screen; Large makes photos easier to recognize. Lists update as soon as you change it.

• Photos are always shown as a square and trimmed to fit, never stretched.
• Each line on a list card stays on one line. If a name or detail is too long, it ends in "…": open the item to see all of it.
• When the list sits in a narrow pane beside an open item (on a tablet or computer), photos are drawn a step smaller so the text keeps its room.

Region

Tells the app where you fly, so registrations use the right names. United States uses FAA terms. Europe (EASA) calls the registration section UAS Operator Registration (e-ID). Other uses general "operator registration" wording. Until you choose, it follows your device's region. Only the names change: your registrations stay exactly as they are, and the setting is kept on each device.

Region affects registration names only: the Profile section, the add and edit registration screens, the registration requirements, and the registration choice when you edit a model. It doesn't change the language, date or number formats, or currency (each has its own setting), and every certificate type, US and EU, is available in every region.

Currency

The currency purchase prices and maintenance part costs are shown in. Automatic follows your language, for example dollars in English and euros in German. Choosing a currency only changes the symbol: amounts are never converted.

Dark Mode & Temperature

• Dark Mode switches between the light and dark themes.
• Use Fahrenheit shows temperatures in °F instead of °C. Temperatures are stored the same way either way, so you can switch at any time.

Disable Battery Health Indicator

If you don't measure internal resistance (IR), turn this on to remove the Health Status line from every battery pack. Charge status and everything else stay as they are, and any IR you log is still kept. See Battery Health.

Remembered View Choices

Choices you make on a screen are remembered when you come back, even after restarting the app: for example Show Retired, sort orders, date ranges like This Month, Hide Completed on checklists, Hide installed in inventory, and where you leave the divider on a tablet or computer. Filters for one particular model, battery or location start fresh each time.

Profile & Documents

Your Profile keeps your pilot paperwork in one place: certifications, club memberships, registrations and other documents. Drag the sections into the order you like. Anything with an expiry date appears in the notification bell before it expires.

Certifications

• Built in: AMA, FAA Part 107 (with recurrent training), TRUST, EU A1/A3 and EU A2 remote pilot certificates. Anything else, such as a DMFV proof of knowledge, is Other, where you type the name.
• Every certificate has an issue date and an expiry date, or "Does not expire". For the EU certificates, picking the issue date fills in the expiry five years later.
• Add a photo of the card or certificate from your photo library, or take one with the camera (PRO). FREE includes one photo per certification; PRO allows as many as you like.

Club Memberships

• Add each club or association separately, for example your local club and the DMFV.
• Member since and the expiry date are both optional. Leave the expiry empty for a membership that runs until it's cancelled. Tap ✕ on a date to clear it.

Registrations

• In the US this is your FAA registration. In Europe it's your UAS operator registration (e-ID), issued by your national aviation authority (the LBA in Germany), sometimes through an association such as the DMFV. It's a different number from the remote pilot ID on your pilot certificate. The names follow Settings → Region.
• Link models to a registration from the model's edit screen.

Documents

Keep insurance policies and any other paperwork here, with photos or PDFs of the document itself.

• Tap + in the Documents section and choose a type. Insurance has fields for the insurer, policy number, coverage start, coverage tier, premium and payment frequency. Other document has a number, issuer and dates.
• Every document can have a start date and an expiry date, or "Does not expire", plus notes. Its status shows as Valid, Expiring Soon or Expired.
• Attachments: take a photo, pick one from your library, or choose a PDF or image from your files. Photos get the same crop and straighten step as your other photos; tap the crop button to adjust one later. Tap an attachment to view it, zoomed in as far as you need, or use the share button to send it to your insurer or club, or save it elsewhere.
• Your own types: tap the tune button next to the type to open Your document types, then New Document Type. Give it a name, such as "Club flying permit", and add the extra fields it needs: text, number or a pick list. Deleting a type keeps every document made with it.
• Documents sync to your other devices, attachments included, and are part of backups.
• FREE users can keep one of each: 1 certification, 1 membership, 1 registration and 1 document. FREE includes one photo or PDF per record, from your library or files; more attachments and taking a photo with the camera are PRO. Unlimited records and your own document types are PRO. If PRO ends, everything you've added stays, and you can still open it all.

Inventory Purchase Value

Once any inventory item has a purchase price, your profile shows the total inventory purchase value: every price, times the quantity for propellers, across everything in your inventory, installed or not. It also shows how many items have a price. See Purchase Prices.

Aircraft Overview Statistics

Each aircraft card in the list displays quick statistics:

• Total Flights - Including baseline + logged flights
• Total Flight Time - Cumulative hours and minutes
• Maintenance Alerts - URGENT, DUE SOON, OPEN badges

Example: "125 flights • 47h 32m"

💡 Tip: Set a baseline flight count and time for used aircraft to track complete history!

Transmitters & Switch Maps

How Switches Are Organized

Switch information lives in two places, because two different things are being recorded:

• The transmitter holds its switches — their names, types and number of positions — and the switch map showing where each one sits on the radio. These never change from model to model.
• Each model holds its switch assignments — what every position of every switch does on that model, such as Pos 0: gear up, Pos 1: gear down.

Set the transmitter up once, and every model you attach to it starts with the same switch list, ready to fill in.

Adding a Transmitter

1. Open Transmitters from the main navigation and tap add
2. Enter the Brand and Model (for example, Futaba T18SZ or Spektrum NX8)
3. Choose the Mode:
   • Mode 1 or Mode 2 for stick radios
   • Surface for pistol-grip radios with a wheel and trigger
4. Optionally fill in the serial number, in-service date, channels, firmware, battery information, a manual URL, notes and a photo
5. Add the radio's switches in the Switches section (below), then tap Save

Adding Switches

1. In the Switches section, tap Add Switch
2. The Switch Name is filled in with the next unused letter. Keep it, or use the name printed on your radio — SA, SB, Gear, Flaps and so on. Each name must be unique on the transmitter.
3. Choose the Switch Type:
   • 2-Position Switch — fixed at 2 positions
   • 3-Position Switch — fixed at 3 positions
   • Momentary (Push Button) — two states, not pressed and pressed
   • Rotary Dial (Variable) — enter how many positions the dial has
   • Other (Custom) — enter any number of positions
4. Tap Save & Add Another to keep the dialog open for the next switch, or Save when you're done. The type and positions carry over to the next switch, so a row of identical switches goes in quickly.

To change or remove a switch later, use Edit Transmitter and the edit or delete icons beside it.

The Transmitter Screen

• Switch Configuration lists every switch with its type and positions, and has the Switch Map button once there are switches to map
• Used With lists every model the transmitter is attached to, with each model's photo or type icon. Tap one to open it. Retired models are included and marked Retired, so you can still find an old model's switch setup from its radio.

Setting Up a Model's Switches

1. Open a model and find its Radios section
2. Add a radio setup and choose the Transmitter under Select Transmitter
3. The transmitter's switches appear under Switch Assignments, one card per switch with a line for each position
4. Tap a position to type what it does — flaps 5%, gear down, throttle cut — or tap the edit icon on a switch to fill in all its positions at once
5. Tap Save

A position left empty shows as (not configured). The buttons beside Switch Programming do the rest:

• Add Switch — adds a switch for this model only, for something the transmitter's list doesn't cover. Model-only switches can be deleted from the model; the transmitter's own switches can't.
• Sync with Transmitter — brings the model up to date after you've added or changed switches on the transmitter. New switches are added, changed ones are updated, and what you've already typed for each position is kept.
• Copy from Another Model — pick another model on the same transmitter and its switch assignments are copied over, ready to adjust. If this model already has assignments, you're asked before they're replaced. Nothing is kept until you save the radio setup.

Choosing a different transmitter replaces the model's switches with the new transmitter's list. Choosing None removes the radio setup from the model, after asking first.

Switch Maps — Where Every Switch Is

A switch map is a photo of your transmitter with a pin on every switch. No more guessing which switch is which when the letters have worn off — or were never printed. Open it with Switch Map on the transmitter screen or the edit screen.

Each map has two views, so switches on the top of the radio can be pinned as easily as those on the face:

• Stick radios — a Front photo, square to the radio with both sticks in view, and a Top photo looking straight down at it
• Surface radios — a Side photo of the left side, with the wheel and the grip in view, and a Top photo

A transmitter whose Mode is Surface starts with a surface map. To change it, use Radio type in the map's menu. Changing type keeps the photos but clears their reference points and pins, since those belong to the other kind of radio.

Creating a Switch Map

1. Add a photo for the current view:
   • Take photo with guide (iPhone, iPad and Android) — the camera shows an outline of the radio to fill, so the radio fills the picture
   • Choose a photo — pick one from your files, then crop, zoom and straighten it before it goes on the map
   • Use the transmitter photo — reuse the photo already on the transmitter
2. Tap two reference points. These line the photo up with the map, so it can be taken from any angle or distance. The app tells you where, as Step 1 of 2 and Step 2 of 2:
   • Stick radio, front: the left stick, then the right stick
   • Stick radio, top: the leftmost top switch, then the rightmost top switch
   • Surface radio, side: the steering wheel, then the bottom of the radio, below the grip
   • Surface radio, top: the steering wheel, then the bottom of the grip
   Tap the center of each, then drag the points to fine-tune them. Pinch or scroll to zoom in.
3. Place the pins. Pick a switch in the list, then tap where it is on the photo. The next switch is selected for you, so you can work around the radio tap by tap. Drag a pin to move it.
4. Switch to the other view and repeat for the switches on that side of the radio. A pin can also be moved between views with Move to top or Move to front in its options.

The map's menu can replace the current view's photo, Redo reference points or Clear pins on that view. The tips at the top of the screen can be hidden and brought back with the help icon.

Using the Map From a Model

1. On a model, tap a switch pill in its radio's Switch Programming area — or anywhere in that area
2. The transmitter opens with every switch pinned. The switches this model uses stand out; the rest are marked Not used on this model.
3. Tap a switch on the radio or in the list to zoom in on it and see what each of its positions does on this model
4. Every switch in the list shows a close-up of its spot on the radio

Use the label button to show every switch's label at once or only the selected one, the zoom and full-screen controls to look closer, and the layout button to put the photo and list side by side or one above the other. If the transmitter hasn't been mapped yet, Map switch locations takes you straight to the map editor.

Sync & Backup

• Transmitters, switches, switch assignments and switch maps sync across your devices for PRO users
• Everything is included in export and import backups

Tips & Best Practices

• 🏷️ Name switches the way your radio does — if the transmitter labels them SA, SB, SC, use those names so the app and the radio's own menus match
• 🗺️ Map the transmitter once — the map belongs to the radio, so every model on it gets the map for free
• 🔁 Start a new model from an old one — Copy from Another Model is the quickest way to set up a model that flies like one you already have
• 🔄 Sync after changing the transmitter — added a switch to the radio? Tap Sync with Transmitter on each model to pick it up
• 📷 Fill the outline — a photo where the radio fills the frame makes pins easier to place and close-ups easier to read

Component Inventory System

What is the Component Inventory?

The Component Inventory is a centralized warehouse for all your RC components. Instead of only tracking components as "part of an aircraft," you can now:

• Store components in a central inventory before installing them
• Track components that move between different aircraft
• Keep spare parts organized and ready for use
• View installation history for each component
• Quickly find available components when building or repairing

Accessing the Inventory

1. On a phone, tap the More menu at the top of the screen, then Inventory
2. On a tablet or computer, tap the 📦 Inventory button in the top bar
3. View all your inventory organized by component type

Supported Component Types

The inventory system supports these component categories:

• Engines / Motors - Glow, gas, electric and turbine power systems
• Gyros / Stabilizers - Flybarless units, stabilization systems
• Receivers - Radio receivers for all protocols
• Servos - All sizes and types of servos
• ESCs - Electronic speed controllers
• Propellers / Blades - Props, rotor blades, fans
• Receiver Batteries - Receiver packs and backup batteries

Adding Components to Inventory

1. Open Component Inventory
2. Expand the category you want (e.g., Engines)
3. Tap Add Engine (or relevant component)
4. Fill in component details:
   • Nickname - Easy identifier
   • Brand/Manufacturer
   • Model/Part Number
   • Serial Number (optional)
   • Specifications (varies by component type)
   • Notes
5. Tap Add to Inventory

Component Status

Each component shows its current status:

• Available - In inventory, ready for use
• Installed - Currently on an aircraft (shows aircraft name)

Installing Components on Aircraft

Method 1: From Aircraft Detail Screen

1. Open an aircraft's detail screen
2. Go to the component section (e.g., Engines)
3. Tap Add from Inventory
4. Select an available component
5. Component is now installed and linked

Method 2: Add New + Copy from Inventory

1. In aircraft detail, tap Add Component
2. Tap Copy from Inventory button
3. Select a component to copy details from
4. Modify as needed and save

Moving Components to Inventory

When you remove a component from an aircraft, you can return it to inventory:

1. Open the component on the aircraft
2. Tap 3-dot menu (⋮)
3. Select Return to Inventory
4. Component returns to inventory as "Available"

Viewing Installed Components

From the inventory screen, you can see where components are installed:

• Installed components show an orange "Installed on [Aircraft Name]" badge
• Tap to view the component details
• Tap View on Aircraft to jump to that aircraft

Installation History

The system tracks installation metrics:

• Times Installed - How many times the component has been installed
• Date Installed - When the current installation occurred
• This helps track component usage and wear over time

Keeping a Complete Parts List

Your inventory can list every part you own: spares and the parts installed on your models.

• Also add to inventory: when you create a new engine, ESC, receiver, receiver pack, gyro, servo or propeller on a model, this option is ticked for you (PRO). The part is saved on the model and also recorded in your inventory, marked as installed on that model, so you never enter it twice.
• Parts added before: use Add to Inventory in the part's ⋮ menu on the model screen.
• Catching up a whole fleet: each inventory section shows a row like "3 on your models, not in inventory". Tap Add all, or expand it and add them one by one. A banner at the top counts them across all your models.
• If a matching part is already in your inventory as installed, adding it again reconnects it instead of making a second copy.
• Edits you make to a part on its model also update its inventory record.
• Parts on retired models are left out of the rows and Add all. You can still add them from the model's own screen.

Purchase Prices

• Open any inventory item, including custom category items, and tap Purchase price to record what you paid. Leave it empty if you'd rather not.
• You can price parts that are installed on a model too: the price saves straight away, even though the part's other details are edited on its model.
• For propellers, the price is per propeller, and the total for the quantity is shown beneath it.
• Your profile adds them all up as the total inventory purchase value. The currency symbol comes from Settings → Currency.

Hiding Installed Parts

Tap the eye icon at the top of the inventory to hide installed parts and see only your spares. Each open section shows how many installed items are hidden. Tap it again to show them. The choice is remembered on each device.

Inventory Without PRO

Inventory is a PRO feature, but you never lose what you've recorded. If you've built an inventory and no longer have PRO, you can still open it and see every item. Adding, editing and removing items needs PRO.

Inventory vs. Aircraft Components

Understanding the two types of component management:

📦 Inventory Components:

• Stored centrally, independent of aircraft
• Can be installed/uninstalled from aircraft
• Track full lifecycle across multiple aircraft
• Ideal for components you swap between models

✈️ Aircraft-Only Components:

• Created directly on an aircraft
• Stay with that aircraft
• Can be moved to inventory if needed
• Ideal for permanently installed components

Tips & Best Practices

• ✅ Use nicknames - Makes components easy to identify (e.g., "3GX Main Heli", "Tail Servo #3")
• ✅ Add serial numbers - Helps track warranty and identify specific units
• ✅ Track firmware versions - Especially for gyros and ESCs
• ✅ Use inventory for swappable parts - Engines, gyros, and receivers that move between aircraft
• ✅ Leave permanent parts on aircraft - Hardwired servos, integrated components

Sync & Backup

• ✅ Inventory syncs across all devices (PRO)
• ✅ Included in backup/restore operations
• ✅ Installation status preserved in sync

Custom Inventory Categories

What Are Custom Inventory Categories?

Custom Inventory Categories allow you to create your own fully flexible item categories inside the Inventory module. Unlike the built-in categories (Engines, ESCs, Receivers, etc.), custom categories let you track any type of item or accessory with fields you define yourself — from spare airframes and decals to tools, safety gear, and consumables.

Accessing Custom Categories

1. Open Inventory: the More menu at the top of the screen on a phone, or the 📦 button in the top bar on a tablet or computer
2. Scroll to the bottom of the inventory screen
3. Find the Custom Categories section
4. Tap Manage Categories to create and edit categories

Creating a Custom Category

1. Open Manage Custom Categories
2. Tap + Add Category
3. Enter a Category Name (e.g., "Tools", "Spare Airframes")
4. Optionally add a Description for context
5. Add Custom Fields (see below for field types)
6. Tap Save

Custom Field Types

When defining a category, you can add any number of custom fields. Each field has a type that controls how data is entered and displayed:

• Text — Free-form text input (e.g., "Brand", "Model Number", "Color")
• Number — Numeric input with optional decimal support (e.g., "Quantity", "Price", "Weight (g)")
• Date — Calendar date picker (e.g., "Purchase Date", "Expiry Date")
• Dropdown — Select from a list of predefined options (e.g., "Condition: New/Good/Fair/Poor")
• Checkbox — Boolean yes/no toggle (e.g., "In Stock", "Needs Replacement")

Adding Items to a Custom Category

1. Open Component Inventory
2. Scroll to your custom category under Custom Categories
3. Tap Add Item
4. Enter the item's Name (required)
5. Optionally add a Description and Notes
6. Fill in the custom field values for this item (matching the fields you defined for the category)
7. Tap Save

Editing and Deleting

Editing a Category:

• Go to Manage Custom Categories
• Tap the category to edit its name, description, or fields
• Add, rename, or remove fields as needed
• Changes apply immediately to all items in that category

Editing an Item:

• Open the custom category on the inventory screen
• Tap any item to open its detail view
• Tap the Edit button to modify any field values
• Save when done

Deleting a Category:

• Go to Manage Custom Categories
• Swipe left on the category or tap Delete
• Confirm deletion — all items in the category will also be deleted

Deleting an Item:

• Open the item detail view
• Tap the 3-dot menu (⋮)
• Select Delete Item and confirm

Sync & Backup

• ✅ Custom categories and all items sync across devices (PRO)
• ✅ Included in export/import backup operations
• ✅ Category structure and custom field values fully preserved

Tips & Best Practices

• ✅ Keep category names short and clear — Easy to scan in the inventory list
• ✅ Use Number fields for quantities — Track how many of each item you have on hand
• ✅ Use Date fields for perishables — Track expiry dates for glow fuel, CA glue, batteries
• ✅ Use Dropdown for condition tracking — "New / Good / Fair / Poor" keeps assessments consistent
• ✅ Use Checkbox for quick status flags — "In Stock", "Needs Reorder", "Needs Repair"
• ✅ Group related items — One "Tools" category instead of many single-item categories

Analytics Dashboard (PRO Feature)

What is Analytics?

The Analytics Dashboard provides comprehensive insights into your entire RC fleet, including flight statistics, maintenance tracking, and battery health across all your equipment.

Accessing Analytics

1. On a phone, tap the More menu at the top of the screen, then Analytics
2. On a tablet or computer, tap the 📊 Analytics button in the top bar
3. PRO badge indicates this is a premium feature

📊 Fleet Overview

See high-level statistics for your entire fleet:

• Total Aircraft - Count of active aircraft
• Total Flights - Cumulative across all aircraft
• Total Flight Time - Combined hours and minutes
• Total Battery Packs - All batteries in inventory
• Total Battery Cycles - Cumulative cycles across all packs

📦 Inventory Value

Once your inventory items have purchase prices, Analytics shows what everything cost:

• Total value, and how many items have a price
• Installed on models vs. Spares
• By category: each inventory section's value and share of the total, including your custom categories
• Installed, by model: what the parts on each model cost
• Most valuable: your most expensive items (propellers count their quantity)

Look at particular models: tap All inventory on the card and tick one model or several. Everything on the card (the total, categories and most valuable items) then counts only the parts installed on those models, so you can see what one airplane or a whole group cost to build. Tap ✕ on a model to take it out, or All inventory to go back to everything.

Inventory has no purchase dates, so the screen's date and other filters don't change this card; it has its own model filter instead. Amounts use the currency from Settings → Currency. See Purchase Prices.

Setup Sheets (Cars, PRO Feature)

What Are Setup Sheets?

A setup sheet records how an RC car is configured — ride height, camber, shock oil, springs, differentials, gearing, tires and everything else you adjust. RC Model Manager keeps those sheets with the car, so you can see what is in it right now, get back to a configuration that worked at a particular track, and see exactly what has to change to get there.

Setups appear on cars only. Airplanes, helicopters and drones are unaffected and see no change.

Accessing Setups

1. Open a car from your models list
2. Find the Setups section on the model screen
3. The setup currently in the car is shown there — tap it to expand and read it without leaving the screen
4. Tap Open setups for the full library

Sheets Included

Seven sheets ship with the app, and you can create your own:

• 🏁 2WD Buggy / Truck — 2WD buggies and stadium trucks tune the same way
• 🏁 4WD Buggy / Truggy
• 🔥 Nitro Buggy / Truggy — a 4WD sheet with engine and clutch in place of motor, ESC and battery
• 🛣️ Touring Car
• 🔥 Nitro On-Road
• 🏎️ Pan Car / F1
• ⭕ Oval — pairs values left and right rather than front and rear

Creating a Setup

1. Open Setups on a car and tap New setup
2. Give it a name you will recognize next season — a track, a surface or a feel works better than a date
3. Choose a Template, or pick No template and add one later
4. Optionally record where a borrowed setup came from
5. Tap Create — you go straight into the sheet to fill it in

Filling In a Sheet

• Fields are grouped into sections, collapsed except the first, with a count of how many are filled
• Paired values show both halves under one label — Front and Rear on most sheets, Left and Right on oval, High Speed and Low Speed for nitro needles
• Units can be chosen where they vary — grams, ounces or pounds for weight; millimeters or inches for ride height, droop and shock length; feet or meters for altitude. Nothing is converted; the unit is simply recorded alongside what you measured
• Add Notes for how the car felt and what to try next time
• Record the Track the setup was proven at, and the Conditions of the day — surface, grip, surface condition, layout size, indoor or outdoor, temperatures, altitude and humidity

Applying a Setup to the Car

One setup per car is marked as being in the car. To switch:

1. Open the setup you want, or use Apply to car from the list
2. A change list appears showing only what physically has to change — Shock Oil — Rear: 40wt → 45wt — grouped in the order you would work through the car
3. Confirm, and that setup becomes the one in the car

History — Going Back to What You Ran

You never have to duplicate a setup by hand. Change one and save, and the app keeps the previous state for you:

• Changes on the same race day stay in that day's entry, so adjusting between heats does not clutter the list
• The first change on a new day starts a new entry, leaving the previous day exactly as it was
• A setup you have never run edits in place, so finishing a half-entered sheet creates no history
• Open a setup to see its History — each race day you changed it — and tap any day to view or re-apply it

Linking Sessions to Setups

1. When you log a session on a car, choose the Setup used — whatever is in the car is offered by default
2. Later, open that session and tap the setup to see the car exactly as it was that day, even if the setup has been changed many times since

Events

Setups and sessions group themselves into Events — a venue plus a run of days. Consecutive days merge, so a three-day meeting reads as one event with its days inside it, and each event shows the setup you finished on. Open Events from the calendar icon in the Setups screen.

Keeping the Sheet Itself

Fields will not always hold everything, and some sheets are worth keeping as they are:

• Photograph a paper sheet directly from the app
• Attach an image or PDF you downloaded from a manufacturer or a setup directory
• PDFs open as pages in the same viewer as photographs, with deep zoom so hand-written numbers stay readable
• Attachments are marked in the setup list and can be opened from there or from the model screen without opening the setup

Finding a Setup Again

Tap the search icon in the Setups screen to search by name, track, event, source or sheet. Setups are listed by when they were last saved.

Sync & Backup

• Setups, sheets and attached scans sync across your devices for PRO users
• Everything is included in export and import backups
• Scans are uploaded at high quality rather than being compressed until they are unreadable

Tips & Best Practices

• 📝 Name setups for places and feels, not dates — "Stanton carpet" or "High grip baseline" is far easier to find months later than a date, and the app already tracks when each was saved
• 🏁 Record the track and conditions — the reason to revisit an old setup is usually that conditions have changed, and without them you cannot tell whether it applies
• 🔁 Start from a setup that worked rather than a blank sheet — use New setup from this on your closest match
• 📷 Crop your photos — squaring up and cropping to the sheet edge makes the difference between legible and not
• 🔗 Pick the setup when you log a session — it takes a moment and is what makes the history worth having

Maintenance Tracking

What is the Maintenance Logbook?

A centralized system for recording service on all your equipment:

• Inspections and routine checks
• Repairs and crash damage
• Part replacements
• Firmware updates
• Modifications and upgrades

FREE keeps up to 5 maintenance tasks open (open, in work or overdue) at once; complete or delete one to add another. Logging completed maintenance is unlimited, and PRO removes the limit.

Logging Maintenance

Method 1: From Equipment Detail Screen

1. Open aircraft/transmitter/battery detail
2. Tap Log Maintenance button
3. Fill in maintenance details
4. Save

Method 2: From Logbook Tab

1. Tap Logbook tab
2. Tap + Add Entry
3. Select asset type and specific asset
4. Fill in details
5. Save

Maintenance Categories

The system supports 11 maintenance categories:

• Inspection
• Repair
• Replacement
• Firmware Update
• Cleaning
• Calibration
• Crash Damage Repair
• Modification/Upgrade
• Preventive Maintenance
• Storage Preparation
• Other

Maintenance Status Tracking

Track the progress of maintenance tasks through these statuses:

• Open - Future or planned maintenance
• In Work - Currently being performed
• Closed - Completed maintenance
• Overdue - Past due date (automatic)

Maintenance History Settings

Control what maintenance history is displayed:

1. Go to Settings → Maintenance
2. Choose history filter option:
   • Show All - Display complete history
   • Hide Older Than... - 30/60/90/180/365 days
3. Open/In Work/Overdue tasks always visible regardless of date

💡 Tip: Use the history filter to focus on recent maintenance while keeping your important tasks visible!

Recurring Maintenance vs. One-Time Tasks

Maintenance entries support both one-time planned work and recurring service intervals. Two concepts work together:

• Next Service Due – When this specific task is due
  • "At Hours" – Total hours when this maintenance should be done next
  • "At Cycles" – Total cycles (for batteries) or similar usage counts
  • "On Date" – Calendar due date
  • "At Flights" – Total flight count when this task should occur
• Recurring Maintenance switch – Whether closing this task should automatically create the next task in the series

How to use these together

• One-time planned maintenance (non-recurring):
  • Set the Next Service Due fields for when this job should be performed
  • Leave Recurring Maintenance turned off
  • When you complete the task via Complete Task, the entry is closed and its Next Due values are cleared so it no longer looks like it has a future trigger
• Recurring maintenance (repeating interval):
  • Set the Next Service Due fields for your interval (for example "Every 10 hours" or "Every 50 flights")
  • Turn Recurring Maintenance on
  • When you close the task, the app automatically creates a new open maintenance entry for the same asset using those Next Due values
  • The closed entry keeps its Next Due values for history; the new entry becomes the next active reminder

What the Complete Task button does

• From the maintenance detail screen, the Complete Task button opens the edit screen with status pre-set to Closed
• If Recurring Maintenance is OFF when you save:
  • The task is marked Closed
  • All Next Service Due fields on that closed entry are cleared (hours, cycles, date, flights)
  • No new maintenance entry is created
• If Recurring Maintenance is ON when you save:
  • The task is marked Closed and keeps its Next Due values for reference
  • A new Open recurring maintenance entry is automatically created with the same Next Due settings

💡 Tip: Think of Next Service Due as "when is this job due?" and the Recurring Maintenance switch as "should a new job be created after I complete this one?". This keeps one-time inspections simple while still supporting recurring service intervals.

Battery Management

Key Features

• Shared Battery Packs: one pack can be used with several models
• Battery Sets: group packs you always use together
• Charge Status: how charged each pack is right now, by color
• Health: judged from internal resistance (IR), when you record it
• Cycle Counting: automatic from charges and sessions, or manual
• Photos: a picture of each pack, like your models and transmitters

Adding a Battery Pack

1. Open Batteries and tap +
2. Enter a Nickname (required), plus brand, model and serial number if you like
3. Choose the Chemistry and enter the Cell Count. The Nominal Voltage fills in for you (a 6S LiPo is 22.2 V), and so do the Min V per cell and Max V per cell, with the whole-pack figure shown under each. You can type your own figures instead.
4. Add capacity, C rating, connector and anything else you want to keep
5. Optionally add a photo (see below)
6. Tap Save

💡 Tip: Only the nickname is required. If all you want is to track which pack you flew and how much you used, a nickname and capacity are enough. Charge colors only appear once a voltage has actually been recorded for the pack.

Battery Photos

• On the add or edit screen, use Select to pick a photo, or Camera to take one (PRO). Edit lets you crop or rotate it, and Remove takes it off.
• The photo appears on the pack's card in the Batteries list (tap it to see it full size) and fills the header of the pack's own screen, with its name, size, chemistry and charge status on top.
• Without a photo, the card shows an icon for the pack's chemistry.
• Battery photos sync to your other devices (PRO) and are included in backups.

Logging Charges

1. Open the pack and tap the ⚡ (Add Charge Event) button, or use the menu on its card in the Batteries list, or scan its QR code
2. Start Voltage is filled in with the pack's last recorded voltage. If none has been recorded yet, it's left empty, with the nominal voltage shown faintly as a guide.
3. Tap Full charge or Storage to fill in the end voltage for the pack's chemistry and cell count, or type the voltage your charger shows
4. Add mAh put in, temperature and per-cell IR if you measure them
5. Save. Cycles are calculated for you.

Voltages in Session Logs

When you log a flight or session, each battery used has Start Voltage and End Voltage fields. Both are optional.

• Start Voltage is filled in with the pack's last recorded voltage, from its last session or charge, so you can keep a voltage trail with little typing.
• If the pack has no recorded voltage, the field is left empty and the nominal voltage is shown faintly as a guide. Nothing is saved unless you type a value.
• If you don't measure voltages, just leave these fields empty. The pack simply shows no charge color.

Charge Status

Charge status shows how charged a pack is now, from the most recent voltage you recorded for it, at the end of a session or charge. It appears as a colored dot on the pack's card, on the model screen, when choosing batteries for a log, and on the pack's own screen.

• ● Charged: ready to fly
• ● Storage: at storage voltage
• ● Recharge: partly used
• ● Check: low, charge it soon
• ● Critical: very low, check the pack before using it

The voltages behind each color depend on the chemistry, so a LiFe or NiMH pack is judged by its own figures, not a LiPo's. Per cell:

Chemistry	Charged	Storage	Recharge	Check	Critical
LiPo (and no chemistry set)	4.05 V+	3.75 V+	3.50 V+	3.40 V+	below 3.40 V
LiPo HV	4.25 V+	3.80 V+	3.50 V+	3.40 V+	below 3.40 V
Li-Ion	4.05 V+	3.70 V+	3.40 V+	3.20 V+	below 3.20 V
LiFe	3.45 V+	3.25 V+	3.00 V+	2.90 V+	below 2.90 V
NiMH / NiCd	1.35 V+	1.25 V+	1.15 V+	1.05 V+	below 1.05 V
Lead Acid	2.10 V+	2.05 V+	2.00 V+	1.95 V+	below 1.95 V

A pack with no recorded voltage, or no cell count, shows no charge color at all.

Battery Health

Health is judged from internal resistance (IR), which most smart chargers can measure per cell. Record it when you log a charge.

• Health always comes from the IR recorded with the pack's most recent charge. If that charge included IR, the pack's screen shows Health Status: Optimal, Acceptable, Degraded or Critical, based on the average IR per cell and how far apart the cells are. Larger packs (4000 mAh and up) are held to a lower IR.
• If the most recent charge was logged without IR, Health Status shows a dash (—). Nothing is wrong with the pack; it just hasn't been measured since its last charge. Charge status still works from voltages alone.
• Editing or deleting a charge updates health straight away.
• Don't measure IR at all? Turn on Settings → Disable Battery Health Indicator to remove the Health Status line from every pack. Any IR you do log is still kept.
• IR readings are stored on the device where you log them and don't sync to your other devices yet, so health shows only on that device.

The Battery Screen

Tap a pack to open it. At the top is its header (photo, name, size, chemistry and charge status), followed by:

• Details: brand, model, chemistry, capacity, configuration, voltages, C rating, in-service date and serial number, plus your notes
• Specs: voltages, C ratings, connector and other specifications
• Health: health status (unless turned off in Settings), charge status, cycles, usage and charge counts, and IR
• Charge sessions and usage history
• Maintenance history

At-a-Glance Statistics

Each card in the Batteries list shows:

🆕 External QR Code Import - Universal Compatibility

RC Model Manager now supports importing QR codes from any external source, making it compatible with other RC management systems and third-party QR codes.

What Are External QR Codes?

External QR codes are QR codes generated by other RC systems that contain equipment information:

• ✅ DJI FPV Goggles - Aircraft and setup info
• ✅ Betaflight Configurator - Flight controller settings
• ✅ Spektrum Transmitters - Model configurations
• ✅ Any QR Code - Product labels, custom codes, etc.

Importing External QR Codes

Method 1: Scan Any QR Code

1. Tap the blue QR scanner (floating button)
2. Scan any QR code (doesn't need to be RC-specific)
3. If it's not a native RC Model Manager QR code, the app shows an "Import Generic QR Code" dialog
4. Enter a system name (e.g., "DJI", "Betaflight", "Spektrum", "Custom")
5. Optionally add a system ID (model number, serial, etc.)
6. Select which of your aircraft/transmitter/battery to associate it with
7. Tap Import

Method 2: From Equipment Detail Screen

1. Open aircraft/transmitter/battery detail
2. Look for the link icon 🔗 in the app bar (appears when external QR is associated)
3. Tap the link icon to access external QR management
4. Tap "Scan New External QR Code"
5. Follow steps above

What Happens When You Import?

• Data Association - External QR info is linked to your equipment
• Hybrid QR Generation - Your equipment generates QR codes with both internal and external data
• Cross-System Compatibility - Your QR codes work with both RC Model Manager and external systems
• Sync Support - External associations sync across all your devices
• Single Equipment Selection - Only one piece of equipment can be selected per import
• Disabled Assets - Equipment already linked to external QR codes appears disabled
• Smart Asset Management - Prevents duplicate associations and ensures data integrity

Managing External QR Codes

Once imported, you can manage external QR associations:

Viewing Current Association:

• Link icon 🔗 appears in equipment app bar
• Shows system name, ID, and import date

Editing Association:

1. Tap link icon → "Edit External QR Info"
2. Change system name or ID
3. Save changes

Replacing Association:

1. Tap link icon → "Scan New External QR Code"
2. Scan different QR code
3. Replaces existing association

Removing Association:

1. Tap link icon → "Remove External QR Association"
2. Confirm removal
3. Equipment returns to internal QR only

Universal Compatibility Examples

📱 DJI Integration:

• Scan DJI aircraft QR code
• Enter "DJI" as system name
• Associate with your aircraft
• Your aircraft QR now works with both DJI and RC Model Manager

🚀 Betaflight Setup:

• Export QR from Betaflight Configurator
• Scan with RC Model Manager
• Associate with your flight controller
• Quick access to setup data at the field

🏷️ Product Labels:

• Scan product QR codes on equipment
• Enter "Product Label" or manufacturer name
• Link to maintenance records
• Easy reference for part numbers and specs

Security & Validation

✅ Safe by Design:

• No arbitrary code execution
• Only stores text data you provide
• All associations require manual approval
• External data never overrides internal data
• You control what gets imported and stored

🛠️ QR Code Lifecycle & Asset Management

⚠️ Important: QR codes are permanently tied to your equipment's database ID. This can cause issues when removing and re-adding assets.

What Happens When You Delete Equipment

• QR Code Becomes Invalid - The physical QR code remains attached but points to deleted equipment
• Not Reusable - Same QR code cannot be "reassigned" to new equipment
• Cross-Device Impact - QR codes become invalid across all devices

Re-Adding Equipment Pitfalls

When you add the same aircraft/battery/transmitter back to inventory:

• New ID Assigned - Gets fresh database ID and sync identifier
• Old QR Code Broken - Physically attached QR code shows error: "Aircraft not found or has been deleted"
• Workaround Required - Must generate and attach new QR code
• User Confusion - Same equipment physically, but QR code doesn't work

Retired Assets Warning

Scanning QR codes for retired assets shows a warning dialog:

Dialog Title: "Retired Asset"

Message: "This asset has been marked as retired. Do you want to continue with this action?"

Options: "Cancel" (returns to scanning) or "Continue" (proceeds with action)

• Purpose - Prevents accidental use of retired equipment while allowing intentional continued tracking
• Examples - Log maintenance on retired equipment, add notes for historical reference, etc.
• Asset Types - Applies to aircraft, batteries, and transmitters (not battery sets)

Best Practices

• ✅ Generate QR codes after inventory is stable
• ✅ Consider equipment as "permanent" before applying QR codes
• ✅ Use caution removing assets with physical QR codes attached
• ✅ Be prepared to replace QR codes if equipment is re-added
• ✅ Test QR codes routinely to ensure they're still working

Troubleshooting

Common Issues

App Won't Launch

• Restart device
• Reinstall app
• Check for updates
• Clear app cache

Photos Not Showing

• Check camera permissions
• Verify photo was saved
• Try re-adding photo
• Check available storage

A Battery Shows A Charge Color I Didn't Expect

• The color comes from the last voltage recorded for the pack, at the end of a session or a charge. Open the pack to see it under Charge Status.
• Log a charge with the voltage your charger shows (or tap Full charge or Storage) and the color updates.
• Check the pack's Chemistry and Cell Count: the colors are worked out per cell for that chemistry. See Charge Status.

Battery Health Shows "—" Or Is Missing

• "—" means the pack's most recent charge was logged without IR. Log IR with the next charge to see health again.
• If the Health Status line is gone entirely, Disable Battery Health Indicator is turned on in Settings.
• IR readings don't sync between devices yet, so health only shows on the device where IR was logged.

A Name Is Cut Off With "…" On A List Card

• List cards keep each line to one line so they stay tidy. Open the item to see the full name and details.
• A smaller Thumbnail Size leaves more room for text.

Sync Not Working

• Check internet connection
• Verify account sign-in
• Force sync in settings
• Check sync status
