Question 2

Betaflight Presets (Recovery)

Accepted Answer

This guide walks you through the process of updating your iFlight BNF drone's Betaflight firmware. Follow these steps carefully to ensure smooth operation and avoid issues during the update process.

1. Determine if an Update is Necessary

Evaluate if an Update is Required: In most cases, iFlight BNFs come with stable, tested firmware from the factory. If your drone is flying well, you might not need to update the firmware.
Understand the Risks: Updating firmware can introduce new bugs or incompatibilities. Always consider whether new features or bug fixes are worth the potential risk. If in doubt, research the latest firmware's release notes and reviews from users with similar setups.
Backup Your Current Setup: If you decide to update, always back up your current configuration. This allows you to return to your previous settings if needed. More on how to back up is provided below.

2. Preparations for Firmware Update

Install Betaflight Configurator:
- Download the latest version of the Betaflight Configurator from the Betaflight GitHub Releases page.
- Choose the appropriate version for your operating system (Windows, Mac, or Linux), and install the program following the instructions.
Connect the Drone to Your Computer:
- Use a USB cable to connect your iFlight BNF to your computer.
- Ensure that the correct USB drivers are installed. Windows users may encounter driver issues, which can be resolved using tools such as the ImpulseRC Driver Fixer to automatically install the necessary drivers for ARM chips like F4**, F7** or H7** flight controllers.
- If you own a bind-and-fly (BNF) drone with an ATF flight controller (for example ATF435) you'll need to install the Artery chip drivers manually. This can be done trough a Google search to find related tutorials or you can also checkout our Helpdesk section 'Troubleshooting'.
Backup Your Current Configuration:
- In Betaflight Configurator, navigate to the Presets Tab.
- Click "Save Backup" to save your current confiiguration.
- Make sure the file just created is not empty.

3. Choosing the Correct Firmware

Identify Your Flight Controller:
- Check your drone’s flight controller model to ensure you choose the correct firmware. You can find this information by connecting your drone to the Betaflight Configurator and checking the top left section or looking at the flight controller documentation.
Selecting the Firmware:
- In Betaflight Configurator, go to the Firmware Flasher Tab.
- Select your flight controller target from the dropdown menu. For example, an iFlight controller might use a target like "IFRC_F7" or similar. You can also use the button "AUTO" to assign the correct firmware selection to your currently installed firmware.
- Choose the latest stable firmware version unless you have specific needs for a different version.
Enable Full Chip Erase:
- Ensure that you check the "Full Chip Erase" option before flashing the firmware. This clears old data, preventing conflicts between old and new firmware.

4. Flashing the Firmware

Enter Bootloader Mode:
- Most flight controllers will enter bootloader (DFU) mode automatically when connected to Betaflight Configurator after you click the "Flash Firmware" button.
- If DFU mode is not entered automatically, press and hold the boot button on your flight controller while connecting the USB cable to force it into bootloader mode.
- Betaflight Configurator should detect this as DFU mode, indicated in the lower right corner of the screen.
- If DFU mode is still not active, this may need to be be resolved by installing the correct drivers using tools such as the ImpulseRC Driver Fixer.
Select your Radio Protocol:
- Betaflight version 4.4.1 and newer will only allow one protocol to be installed. Select "CRSF" for ExpressLRS (ELRS) or TBS Crossfire receivers. Select "SBUS" for DJI FPV RC users.
Load Firmware:
- Click on "Load Firmware [Online]." This downloads the selected firmware from the Betaflight server.
Flash the Firmware:
- After the firmware is loaded, click "Flash Firmware" to begin the update. Ensure that the process is not interrupted. Once completed, the flight controller will automatically reboot with the new firmware installed.

5. Adding iFlight Factory Recovery Presets (Recommended)

If you wish to recover the factory-tuned iFlight settings for your drone, you can use the iFlight Factory Preset Library. Follow the steps below:

Access the Presets Tab:
- In Betaflight Configurator, navigate to the Presets Tab.
Add iFlight Factory Recovery Source:
- Click on the "Add New Source" button.
- Copy and paste the following text exactly as it appears (without any backspace or empty space at the beginning or end of each line):
  - iFlight Factory Recovery
  - https://github.com/Jason-iFlight/firmware-presets
  - iFlight
- Set the new preset source to "Active".
Select the Correct Preset:
- After adding the iFlight source, you will see a list of presets specifically tuned for iFlight drones in the category BNF. Select the appropriate preset for your drone model.
- Every preset has a firmware version that has to match the currently installed firmware on your flight controller.
- Read the preset text carefully and follow the steps to apply!
- Click "Save and Reboot".

7. Testing Your Drone After Update

Initial Test Flight:
- After flashing the firmware and restoring your configuration, perform a test flight in a safe environment.
- Start with basic hovering and light maneuvers to ensure stability. Check for any issues, such as motor desyncs, poor flight performance, or abnormal behavior.
Tuning and Adjustments:
- If any issues arise, revisit Betaflight Configurator and fine-tune settings, such as PID tuning, filters, or rates, to match your flight style.

Other iFlight BNF models:

If you have an unlisted or older iFlight Bind-And-Fly drone model then you might not find a current Betaflight factory preset on our Github database. Please use the following Google Drive Database to download your factory dump file: https://drive.google.com/drive/folders/1jQlSfYY74gaQku_EMYRsBpU7gqcCcCZK

Optional: Restoring and Configuring Your Drone

Restore Configuration:
- You can restore your previous settings by returning to the Presets Tab and click "Load Backup" to restore your settings. Use the file that was created with "Save Backup" to load and apply. Make sure that the firmware version from the backup matches your currently installed firmware, otherwise you'll receive errors.
Check Basic Settings:
- Check your drone's basic settings, such as arming modes, PID values, motor protocols, and any custom configurations like Betaflight OSD.
Calibrate the Accelerometer:
- If your flight controller includes an accelerometer, go to the Setup Tab in Betaflight and click "Calibrate Accelerometer." Ensure your drone is on a level surface while performing this step.
Check ESCs and Motors:
- Confirm that your ESC (Electronic Speed Controller) protocol (such as DShot or Multishot) is correct under the Motor Tab. Perform an ESC calibration if necessary to ensure smooth motor performance.

Question 3

FPV drone doesn't arm

Accepted Answer

If your quadcopter is not arming, follow this detailed guide to troubleshoot and resolve the problem.

Step 1: Check the Battery

Before troubleshooting further, always ensure that:

The battery is fully charged.
The battery is properly connected to the quadcopter.

A low or improperly connected battery can prevent your quadcopter from arming due to insufficient power. To check:

Use a voltage checker or monitor the battery voltage in Betaflight Configurator (or similar software).

Step 2: Transmitter and Receiver Binding

Ensure that your transmitter (remote control) and receiver are properly bound and communicating with each other. If they are not, your quad will not arm.

To check if they are bound:

Verify that your transmitter displays the correct model.
Look for any indicator lights on the receiver showing it is receiving a signal.
Test other transmitter functions like moving the throttle or pitch, and confirm that the receiver reacts.

If they are not bound:

Follow the binding instructions specific to your transmitter and receiver model. This usually involves holding a button on the receiver and binding via the transmitter menu.

Step 3: Throttle Position Check

The most common reason for arming issues is the throttle stick not being at the lowest position. Quadcopter flight controllers have built-in safety features that prevent arming if the throttle is too high.

Steps to Check:

Move the throttle stick to the lowest possible position.
Ensure that the transmitter endpoints are correctly calibrated (you’ll do this in a later step if necessary).
Some transmitters allow you to set the Throttle Trim; ensure this is also set to the lowest value.

Step 4: Check Flight Mode Selection

Make sure you are in an appropriate flight mode that allows arming. Some flight controllers are configured not to arm in certain modes.

Flight Mode Verification:

Angle Mode is the safest and most common flight mode for beginners, allowing for automatic leveling.
Ensure that you’re not trying to arm the quadcopter in a mode like Horizon Mode or Acro Mode, unless you are confident those modes have been correctly configured.

Tip: Verify which flight mode is selected in your transmitter or Betaflight Configurator.

Step 5: Pre-Arming Safety Features (Arming Flags)

Your flight controller has safety checks that must be met before it allows arming. These are called arming flags, and they can prevent arming for various reasons.

To check arming flags in Betaflight:

Connect your quadcopter to the Betaflight Configurator via USB.
Go to the Setup tab and look for an “Arming Disabled” message. This message will indicate what is stopping the arming process.

Common arming flags include:

Throttle too high: Throttle stick must be at its lowest position.
Accelerometer calibration needed: You need to calibrate the accelerometer (next step).
Bad receiver signal: Check your receiver is working and bound to the transmitter.
Failsafe enabled: The quad detects a signal loss, preventing arming (more on this below).

Step 6: Calibrate the Accelerometer

If the accelerometer is out of calibration, your quadcopter may not arm. This is a common issue, especially if you’ve made changes to the flight controller or had a crash.

Steps to calibrate in Betaflight:

Connect the quadcopter to Betaflight Configurator.
Go to the Setup tab.
Place the quadcopter on a flat surface.
Click “Calibrate Accelerometer”. The flight controller will now align itself to the level surface.

Tip: Always ensure that the quadcopter is stable and flat during calibration to avoid drift during flight.

Step 7: Failsafe Settings

Failsafe settings prevent the quad from arming if it detects that the receiver is not functioning properly or if signal strength is too low.

To check for failsafe issues:

Ensure that your receiver is correctly bound and that the failsafe settings in Betaflight are configured.
In Betaflight Configurator, go to the Failsafe taband review the settings.
- By default, the failsafe should trigger if signal loss occurs.
- Ensure that “Stage 1” is set to Land or Drop (depending on your preference) rather than Disarm, which would prevent arming entirely.

Step 8: Check for GPS Lock (if applicable)

If your quadcopter is equipped with GPS, arming might be prevented until a sufficient number of satellites are locked.

How to check GPS lock:

Ensure you are outside in an open area.
Wait for your quadcopter to lock onto at least 5-6 satellites.
You can check the number of satellites in Betaflight Configurator or on the OSD (On-Screen Display) if it’s configured.

Step 9: Verify Motor Stop Functionality

The Motor Stop feature might make it seem like the quadcopter isn’t arming, even though it actually is. This setting prevents motors from spinning immediately after arming.

To check Motor Stop settings:

Connect to Betaflight Configurator.
Go to the Configuration tab.
Look for the “Motor Stop”option.
- If this option is checked, the motors will not spin upon arming.
- Uncheck it if you want the motors to spin when the quad is armed.

Step 10: Check Transmitter Endpoints

Your transmitter’s channel endpoints must match what the flight controller expects. Incorrect endpoints can prevent arming due to invalid input values.

Steps to check and calibrate endpoints:

Go to the Receiver tab in Betaflight Configurator.
Move the throttle, yaw, pitch, and roll sticks to their maximum and minimum positions.
Ensure that all channels go from 1000 to 2000 (or close to these values).
If they don’t, you’ll need to adjust the subtrim and endpoints on your transmitter until the values align.

Step 11: Inspect ESCs and Motors

Hardware issues like faulty Electronic Speed Controllers (ESCs) or motors can also prevent arming.

Steps to check:

Inspect the wiring to ensure all ESCs are connected properly to the flight controller.
Check for any damage or loose connections.
If necessary, recalibrate the ESCsusing Betaflight Configurator:
- Go to the Motors tab.
- Follow the ESC calibration steps (with props removed for safety).

Step 12: Update Flight Controller Firmware

Sometimes, bugs or outdated firmware can cause arming issues.

Steps to update the firmware:

Connect your quadcopter to Betaflight Configurator.
Go to the Firmware Flasher tab.
Download and flash the latest firmware version for your flight controller model.
Follow the instructions carefully to avoid bricking the controller.

Step 13: Review the Flight Controller's Manual

If none of the above steps work, refer to your flight controller’s user manual for model-specific instructions or troubleshooting tips. Some flight controllers have unique settings that might block arming under certain conditions.

Step 14: Common Arming Error Messages and Their Solutions

Here’s a quick overview of common error messages and how to fix them:

Throttle Too High: Ensure the throttle is fully down and recalibrate endpoints if necessary.
Failsafe: Ensure receiver is bound and failsafe settings are properly configured.
No GPS Lock: Wait for sufficient satellite lock if using GPS.

Step 15: Contact Our Support Team

If none of the above steps resolve the issue, please reach out to our support team for further assistance. Be sure to provide:

Your flight controller model.
Your transmitter model.
Any error messages you see in Betaflight Configurator.

Question 4

QuickStart Guide

Accepted Answer

Congratulations, you have just purchased your first iFlight BNF. We wish you save flights and a great time with your quadcopter.

We have some short steps to follow:

Step 1: Don't put your propellers on!

Leave the spin direction markers on the motors. We will need those for the last step putting on the propellers.

Step 2: Bind the receiver installed in your BNF to your transmitter.

Most quads can power the receiver through the USB cords. If you don't see the receiver LED come up, try again with a battery to confirm a.) if its powered on and b.) its position. The flight controller (FC) sits always around the center, the receiver (TBS Crossfire or ELRS) is about as big as your thumb and sits in the front or back, top or bottom mounted.

ATTENTION: Never plug in a battery if there is no antenna installed on your quad. This can possibly damage your video transmitter but also leads to overheating. Always keep the battery plugged in as short as possible if no cooling applied to the drone.

DJI FPV Radio Controller (RC2, RC3) do not have a separate receiver. The DJI video transmitter has an inbuilt receiver which connects to Goggle and Radio Controller. This can only be powered on by plugging in the battery.

If you don't know how to bind your receiver to your radio transmitter, please don't skip Step 3.
Skip Step 3 if you've already linked everything together.

Step 3: Follow Up with our Binding Guides

We have separated Setup Guides for ELRS, TBS Crossfire or DJI Radio Controllers. You'll know what you need to select.

Please come back after binding your receiver to your radio transmitter.

Step 4: Download and install the Betaflight Configurator

Step 5: Connect your computer to your drone with an USB cable.

Step 6: Download ImpulseRC driver fixer if you're on a windows computer.

Open the file while being connected to your drone. The tool will automatically detect the flight controller and install the windows drivers for Betaflight.

Step 7: Open the Betaflight Configurator.

We have to do some simple steps to doublecheck your equipment. Every iFlight BNF comes with a factory setup that contains a lot of settings to configure the flight controller, but also so called tune and filter setups that make your drone fly well.

Sidenote:

You don't need to change anything, you also don't need to update anything. If you plan to update, there is a separate advanced Guide which we don't need now. Updates should only be performed by advanced users with experience. Never try an update before doing some flights on the factory setup first.

Step 8: Quick Check:

On the first screen, you can see the drones' orientation, nothing to check here. Click on the 'Receiver' tab and confirm that your radio transmitter is correctly sending inputs. Plug in your battery to hear your drone bootup the first time. Try if the throttle stick is moving the throttle indicator.

Click on 'Modes' tab to setup your arming button. The standard for most people would be AUX1, and this is also recommended due to some technical aspects of the software. For DJI Radio Controllers please use any button you like to arm. To assign a AUX channel just click on the Dropdown in the Arm field and select AUTO, then move the button you want to link.

Angle Mode is activated by default across the entire selection range of channel AUX2. If you don't want to use this leveling mode just smaller the selection range and assign AUX2 to a button on your radio controller to activate or deactivate this function at any time.

Question 6

Setting up GPS Rescue

Accepted Answer

This guide will help you set up GPS Rescue Mode in Betaflight to ensure your drone can return to a designated home position in case of signal loss. This feature is especially useful in long-range flying scenarios. Follow the steps carefully to configure GPS Rescue on your quadcopter.

1. Prerequisites

Before getting started, ensure the following:

Your quadcopter is equipped with a GPS module compatible with Betaflight (such as BN-180 or BN-220).
You are running Betaflight version 4.1 or later. Older versions may not have full GPS Rescue functionality.
If you're using a M10 GPS module it's recommended to upgrade Betaflight to Version 4.5 or newer.

2. Hardware Setup: Installing the GPS Module

Mount the GPS module on your quadcopter in an open area, away from interference like your VTX (video transmitter) or antennas. It’s usually placed at the rear of the quad to get a clear satellite signal.
Wire the GPS moduleto your flight controller (FC). Use a UART port (TX and RX pads) on your flight controller.
- GPS TX → FC RX
- GPS RX → FC TX
- Power the GPS by connecting it to a 5V and GND pad.
Double-check the wiring connections before moving on to configuration.

3. Configuring the UART Port for GPS in Betaflight

Connect your flight controller to your computer and open Betaflight Configurator.
Navigate to the Ports tab.
Find the UART port where you connected the GPS module.
- In the “Peripherals” column of that UART, select GPS from the dropdown menu.
Click Save and Reboot to apply the changes.

4. Configuring GPS Settings in Betaflight

Once the FC has rebooted, go to the Configuration tab.
Scroll down to the GPS section.
Toggle ON the GPS option.
Set the correct GPS protocol:
- Most GPS modules use the UBLOX protocol, so select this unless your GPS specifies something different.
If your GPS module includes a magnetometer (compass), enable it by toggling Magnetometer (optional).
Click Save and Reboot.

5. Calibrating and Testing the GPS

Wait for GPS lock:
- It may take a few minutes for your GPS module to get its first lock on satellites (especially in a new location).
- You’ll need a minimum of 6 satellites to fly safely. For better accuracy and performance, aim for more than 8 satellites.
Go to the Betaflight OSD or use the GPS tab in the configurator to check the number of satellites, GPS coordinates, and other information. Ensure everything is functioning correctly before proceeding.

6. Setting Up GPS Rescue Mode in Failsafe

In Betaflight Configurator, go to the Failsafe tab.
Under Stage 2 Failsafe Procedure, select GPS Rescuefrom the dropdown menu.
- This means that when your drone loses connection with the transmitter, GPS Rescue will automatically trigger and return the quad to the home position (where it last acquired a GPS lock before takeoff).
Fine-tune GPS Rescue parameters:
- Minimum Satellites for Fix: Set this to at least 6 to ensure GPS Rescue only activates when there’s a solid GPS lock.
- Initial Climb Height: Set this to around 100m (or higher) to ensure the quad climbs to a safe altitude before heading home.
- Descent Speed: Set this to a reasonable value (e.g., 50 cm/s) for a controlled descent.
- Max Home Distance: This limits the maximum distance for GPS Rescue to engage. If your quad is beyond this distance, Rescue won’t activate.
Click Save and Reboot.

7. Optional: Assigning a Manual GPS Rescue Switch

You can manually activate GPS Rescue Mode by assigning it to a switch on your transmitter.

Go to the Modes tab in Betaflight Configurator.
Look for GPS Rescue and assign it to an AUX channel that corresponds to a switch on your transmitter.
Adjust the range so that when you flip the switch, the GPS Rescue Mode is triggered.
Click Save.

8. Testing GPS Rescue Mode

Before flying with GPS Rescue, it is crucial to test it in a controlled environment.

Check home position: Before arming your quad, ensure that you have a proper GPS lock and that the home position (where the quad took off) is recorded. You can monitor this in the Betaflight OSD or via the Configurator.
Test GPS Rescue in manual mode:
- Fly your quad in a safe, open area with a good GPS signal.
- At a safe altitude, activate the GPS Rescue switch (if set up) or simulate failsafe conditions (e.g., by turning off your transmitter momentarily).
- Watch to see if the quad gains altitude, turns towards the home point, and begins to return.
Check the failsafe behavior:
- After GPS Rescue is triggered, verify that your quadcopter climbs to the specified altitude, returns to the home position, and begins descending.
- Once the quad gets close to the home point, you can regain control by reactivating your transmitter or disarming the quad manually.
Testing failsafe:
- Set up a soft failsafe to see if the GPS Rescue activates when the transmitter loses signal.

9. Troubleshooting Tips

Not getting GPS lock? Check the wiring of your GPS module and make sure it's placed away from interference. Re-check if the correct protocol (UBLOX) is selected in Betaflight.
GPS Rescue not climbing high enough? Double-check the settings in the Failsafe tab, especially the Initial Climb Height.
GPS Rescue drifting? Ensure that you have a solid GPS lock before takeoff (at least 6 satellites). More satellites will provide more accurate positioning.
Quad doesn’t return to home point? Check the Home Distance setting and make sure that the home point is being set correctly before arming.

Final Notes

Always test GPS Rescue Mode in a controlled environment before relying on it in critical situations.
GPS Rescue is not foolproof and can be affected by the environment, poor GPS signal, or incorrect configuration. Use it as a last resort for failsafe, and always fly responsibly.

Question 7

Can't connect to Betaflight

Accepted Answer

If you’re having trouble connecting your flight controller to Betaflight, the issue is often related to missing or incorrect drivers. Follow these steps to resolve the issue, depending on your chip version.

Step 1: Identify Your Chip (AT32 or STM32)

AT32 (Artery Chip):

These flight controllers are becoming popular due to their affordability. However, they require manual driver installation, as the ImpulseRC Driver Fixer doesn't support AT32. The flight controller name contains ATF.

STM32:

This chip is the most common and usually works well with the ImpulseRC Driver Fixer. The flight controller name contains F4, F7 or H7.

Step 2: Resolving STM32 Driver Issues (Automatic Fix)

If your STM32-based controller isn't detected in Betaflight, follow these steps:

Download the ImpulseRC Driver Fixer:
- Download the tool from here.
- Run the tool while your controller is connected to your computer.
- The tool will automatically attempt to fix any driver issues related to STM32 flight controllers.
Ensure You Have the Correct COM Port Drivers:
- STM32 flight controllers typically require virtual COM port drivers, which are usually installed by default. If not, they can be downloaded from the STM website.

Step 3: Resolving AT32 Driver Issues (Manual Fix)

For AT32 controllers, drivers must be installed manually. Follow these steps to ensure proper installation:

Download the AT32 Virtual COM Port Driver:
- Go to the Artery AT32F435 MCU page.
- Download and install the Virtual COM Port Driver to enable communication between your PC and the flight controller.
- Restart your computer after installation.
Install DFU Drivers for Firmware Flashing:
- To enable DFU mode (Device Firmware Update) for flashing firmware, download the Artery ISP Programmer from the same page.
- Install the software and restart your computer.
Check Device Manager:
- After installing the drivers, connect your AT32 controller and open Device Manager (Windows key + X > Device Manager).
- You should see the controller listed under Ports (COM & LPT) or Universal Serial Bus Devices.
Test in Betaflight:
- Open Betaflight and try connecting your flight controller. It should now be recognized if the drivers are correctly installed.

Step 4: Additional Troubleshooting

Try a Different USB Cable: Sometimes connection issues are related to faulty cables, especially if they’re charge-only.
Reinstall Betaflight: If driver issues persist, reinstalling Betaflight can also resolve connection problems.

Question 10

Setting up ExpressLRS / ELRS

Accepted Answer

Step 1: Power On the Receiver

When powering on an ExpressLRS receiver for the first time, it typically enters bind mode automatically if it has not been paired before. This is indicated by a double-blinking LED. iFlight BNFs with ELRS receivers have been paired before at the factory for quality control inspection.

Step 2: Binding / Linking of your radio controller and FPV drone receiver

There are several ways to bind your ELRS receiver to your transmitter, but we recommend using the binding phrase method. By flashing both the receiver and transmitter with the latest firmware, you can set a binding phrase—often referred to as an 'ELRS password'—for your equipment. This approach makes it easy to add new FPV drones or receivers to your setup. All you need to do is flash each new receiver with the same binding phrase, and it will seamlessly integrate into your fleet.

Method 1: Set the Binding Phrase (Recommended)

ExpressLRS offers a feature called the binding phrase, which simplifies the binding process. You can set this phrase during the firmware flashing process for both the transmitter and receiver. Once configured, the devices will automatically bind when powered on. Ensure that the same binding phrase is used for both the receiver and transmitter to allow automatic binding.

Alternatively, if your receiver has WiFi capabilities, you can connect to it via its onboard WiFi. Once powered on, the receiver will broadcast a WiFi signal. Connect to this network, access the web interface, and adjust settings like the binding phrase.

Method 2: Use the Receiver’s Bind Button

Only for ELRS firmware 3.4.1 or newer! Some receivers have a physical bind button. Press and hold this button for 2-3 seconds to activate bind mode. The LED will blink, signaling that the receiver is ready to connect to a transmitter. If your receiver doesn’t have a bind button, proceed to the power-cycling method in the next step.

Method 3: Three-Power-Cycle Method

For receivers that don’t enter bind mode automatically or lack a bind button, use the 3-power-cycle method. Power the receiver on and off three times in quick succession. After the third cycle, the LED will begin blinking rapidly, indicating that it’s now in bind mode.

To finish method 2 or 3: Initiate Binding from the Transmitter

With the receiver in bind mode, you can now initiate binding from your transmitter. If you’ve set a binding phrase, the transmitter should automatically connect to the receiver. Without the binding phrase, you must manually trigger the binding process on your transmitter, for instance, by using the ExpressLRS Lua script on OpenTX/EdgeTX radios.

Steps to bind manually:

Access the transmitter settings on your radio.
Select the “Bind” option to initiate the binding process.
The transmitter will now search for the receiver and establish the connection.

Final: Confirm Successful Binding

Once binding is successful, the LED on the receiver will stop blinking and remain solid. This indicates that the receiver is now connected to the transmitter and ready for use.

Optional Troubleshooting

If binding is unsuccessful:

Verify that the firmware on both the transmitter and receiver is updated and compatible.
Ensure both devices are using the same binding phrase.
Retry the 3-power-cycle method to re-enter bind mode.

Question 17

FPV Battery Charging, Discharging, Storage

Accepted Answer

FPV (First-Person View) drones are powered by lithium polymer (LiPo) batteries, which are known for their high energy density, lightweight nature, and ability to deliver high currents. However, LiPo batteries also require specific care to ensure their longevity, performance, and, most importantly, safety. Improper charging, discharging, storage, and handling of these batteries can lead to reduced performance, potential battery damage, or even fire hazards. This guide covers the best practices for handling FPV drone batteries to ensure they last long and remain safe for use.

1. Charging FPV Drone Batteries

Charging is one of the most critical stages in maintaining LiPo batteries. Here’s how to do it properly:

Use a Dedicated LiPo Charger: Always use a charger specifically designed for LiPo batteries. These chargers monitor the voltage and prevent overcharging, which is crucial for safety.
Charge in a Safe Environment: LiPo batteries can become volatile if not handled correctly. Always charge your battery in a fireproof bag (LiPo safe bag) and place it on a non-flammable surface like ceramic or metal. Never leave the battery unattended during charging.
Charge at a Safe Rate (1C): "C-rate" is a measure of how fast a battery can be charged or discharged. For safety and to extend battery life, charge your battery at 1C, which means charging at a rate equal to the battery's capacity. For example, if your battery has a 1300mAh capacity, charge it at 1.3 amps. Some batteries can handle faster charging rates, but 1C is the safest standard for long-term use.
Balance Charging: LiPo batteries consist of multiple cells, and it’s essential that each cell is charged evenly. Always use the balance charge mode on your charger to prevent overcharging one cell and damaging the battery. This maintains the health of all cells and ensures maximum performance.
Monitor Voltage and Temperature: Avoid charging batteries above 4.2 volts per cell, which is the safe maximum. Also, ensure that the battery doesn’t get too hot during charging. Excessive heat is a sign of damage or improper charging rates.

2. Discharging FPV Drone Batteries

Discharging your FPV drone battery correctly is vital to maintaining its health and preventing damage:

Avoid Over-Discharging: LiPo batteries should not be discharged below 3.5 volts per cell (under load) or 3.7 volts per cell (at rest). Draining a battery too low can cause irreversible damage to the cells, resulting in reduced capacity or complete failure. Using a low-voltage alarm or OSD (On-Screen Display) in your FPV setup can help you monitor the voltage during flight.
Manage Discharge Rates: High discharge rates are common in FPV drones, especially during aggressive flying. While LiPo batteries are designed to handle these, constantly flying at full throttle can shorten battery life. It's best to fly with a mix of throttle levels to reduce stress on the battery.
Let the Battery Cool Before Recharging: After a flight, the battery will be warm. It’s important to let it cool down to room temperature before charging it again. Charging a warm battery can lead to cell imbalance, overcharging, or even fire hazards.

3. Storing FPV Drone Batteries

Proper storage of LiPo batteries significantly extends their lifespan and ensures they remain safe for use:

Use Storage Charge: LiPo batteries should be stored at a voltage of around 3.7-3.85 volts per cell. Most LiPo chargers have a “storage charge” mode that ensures the battery is neither fully charged nor fully discharged, which helps prevent swelling or deterioration over time.
Store in a Cool, Dry Place: Heat and humidity can cause the battery cells to degrade. Store your batteries in a cool, dry environment, ideally between 10°C and 25°C (50°F and 77°F). Avoid storing them in extreme temperatures, such as in a car or direct sunlight, as this can lead to battery swelling or damage.
Use a Fireproof Container: Although rare, LiPo batteries can become unstable during storage and pose a fire hazard. Store them in a fireproof container or a LiPo-safe bag to minimize the risk of damage to your surroundings in case of a malfunction.

4. Handling FPV Drone Batteries

Safe handling of LiPo batteries ensures they remain in good working condition and reduces the risk of accidents:

Inspect Regularly for Damage: Always inspect your batteries for any signs of physical damage, such as swelling, punctures, or frayed wires. A damaged battery should not be used, charged, or stored with other batteries. If you notice any of these issues, safely dispose of the battery.
Avoid Short Circuits: When handling batteries, ensure that the terminals do not come into contact with each other or any conductive materials. Short-circuiting a LiPo battery can lead to immediate fire or explosion. Always store batteries with their terminals covered or use a protective cap.
Transporting Batteries: When transporting your FPV drone and batteries, ensure they are stored in a protective container, such as a LiPo-safe bag. This will minimize the risk of damage and fire hazards during transportation. When traveling by air, be sure to check regulations regarding carrying LiPo batteries, as they are often subject to restrictions.

5. Battery Disposal

LiPo batteries are hazardous waste and must be disposed of properly:

Discharge Fully: Before disposing of a LiPo battery, it should be fully discharged to minimize the risk of fire. Some chargers have a discharge mode, or you can safely discharge the battery by connecting it to a resistor or a discharge bag.
Recycle at a Designated Facility: Do not throw LiPo batteries in the trash. They contain chemicals that are harmful to the environment. Take your discharged batteries to a local electronics store or recycling center that handles LiPo disposal.

Conclusion

Caring for your FPV drone batteries properly is essential for performance, longevity, and safety. By following the proper procedures for charging, discharging, storing, and handling LiPo batteries, you’ll not only extend their lifespan but also reduce the risk of accidents and ensure a safer flying experience. Always stay vigilant for any signs of battery damage or instability, and never hesitate to take extra precautions when working with these powerful energy sources.
