When an FPV drone's motor halts abruptly, causing the drone to crash, it's often a sign of ESC Desynchronization. This guide explores the causes and provides strategies for correcting ESC desyncs through adjustments in BLHeli and Betaflight configurations no mater you are using sush as 1800KV brushless motor, small drone motor, 2806.5 Brushless Motor..

Understanding ESC Desync

Not every crash signifies an ESC desync. For example, a drone plummeting without spinning might indicate a failsafe or power loss. An ESC desync typically results in the drone spinning or flipping uncontrollably.

Analyzing Blackbox logs is the most effective method to diagnose an ESC desync, characterized by a motor stalling (ceasing to spin, thereby not generating lift), which in turn causes the drone to increase the motor's signal to its maximum 100%.

Without Blackbox, scrutinizing DVR footage closely can also hint at which motor suffered from the desync based on the direction of the drone's roll—the affected motor is usually the first to drop.

Causes of ESC Desync

ESC desync can arise from:

• Motor RPM exceeding the ESC's capability.
• Excessive electrical interference.

A high motor RPM can prevent the ESC from detecting the motor’s “zero crossing” point (commutation), and electrical interference can compound this issue. If the ESC fails to detect the “zero crossing,” it won't know when to activate the next pulse, causing the motor to stall eventually.

Addressing ESC Desync

Mitigating ESC Desync involves adjusting settings in BLHeli and Betaflight. Not all adjustments may be necessary simultaneously, but a combination thereof could resolve the problem.

First and foremost, ensure a low ESR capacitor is soldered to your ESC’s power input to minimize electrical noise, which is often a primary culprit.

BLHeli Adjustments:

• Rampup Power (or Startup Power): Opt for a lower setting, such as 0.125 in BLHeli_S or 12% in BLHeli_32. Increase the rampup power incrementally if the motors stutter upon arming, until the motors initiate smoothly without inducing desync.
• Demag Compensation: Increase to high to enhance the drone's ability to recover from desync episodes, though it might slightly impact performance.

Adjust these settings only if you encounter desync issues.

Betaflight Adjustments:

• DShot ESC Protocol: Switch to DShot if not already in use.
• Motor Idle Throttle Value: The standard setting is 5.5, which may be too low for smaller quads. Consider adjusting to a higher value, such as 6.5 or 7.

Conclusion

By following these strategies, your ESC Desync issues should be resolved, paving the way for fine-tuning your quad with these 10 easy steps

The operation hinges on linking four crucial pins: RX, TX, VCC (5V), and GND (ground), with the RX and TX pins serving the purpose of data exchange.

Step 1 – Preparing the FTDI Dongle

Initiate by pinpointing the COM Port displayed in the ExpressLRS Configurator following the connection of the FTDI dongle to your computer. If a new COM port does not appear, you may need to install the cp2102usb driver.

Step 2 – Linking the Receiver with the FTDI Dongle

Activating the receiver's boot mode is a prerequisite for the FTDI update procedure whether you are using 1900KV brushless motor, 2450KV brushless motor, 11000KV brushless motor or 2004 Brushless Motor.

Typically, this requires pressing and holding the boot button on the receiver while it is being connected to the FTDI Dongle (the button can be released once the LED illuminates). In some cases, creating a temporary solder bridge may be necessary instead of a button press (which should be removed following the flashing operation).

While holding the boot button, connect the receiver to the FTDI Dongle adhering to the following configuration:

• VCC to 5V
• GND to ground
• TX to RX
• RX to TX

For the majority of ExpressLRS receivers, the 5V option is recommended. The Radiomaster UART Flasher is provided with a cable harness for facilitating connections to receivers without solder pads.

When the receiver's LED illuminates continuously, it signifies that it is in boot mode and ready for the firmware flashing process.

Step 3 – Setting Up Through ExpressLRS Configurator

Proceed with the standard configuration steps in the ExpressLRS Configurator, selecting the appropriate firmware version, device category, and the specific model of the receiver. Make sure the UART flash method is chosen. Adjust any other preferences accordingly and double-check the COM port for your FTDI programmer.

Step 4 – Initiating the Firmware Update

Click on ‘Build & Flash’ to begin the firmware updating process. Upon successful completion, the receiver can be disconnected from the FTDI dongle.

Wrapping Up

Becoming adept at FTDI-based firmware updates is invaluable, especially when confronted with difficulties using conventional update methods. This guide aims to provide a structured and straightforward approach to rejuvenating and updating your ELRS RX using an FTDI programmer, such as the specified Radiomaster USB UART Flasher, potentially saving your device from being discarded. Careful attention to your connection setup and configuration choices is essential for a seamless update process.
