Troubleshooting Guide

Having trouble with your XFly Drone? This troubleshooting guide is here to help you quickly identify and resolve common issues. From flashing error LEDs to propeller malfunctions, you’ll find clear and easy-to-follow solutions for keeping your drone in top condition. With this guide, you can troubleshoot problems and get back to flying in no time.

Common issues

1. Error LED flashes continuously.

When the drone is turned on, it first runs an initial system diagnosis and checks for the IMU, ToF, and Optical Flow sensors. If any of these sensors are not responding, the yellow LED starts flashing.

 

To resolve this issue, disconnect the battery, check the optical flow deck to ensure it is securely plugged in, and then reconnect the battery.

2. The drone keeps resetting and flashes the startup LED sequence continuously.

Xfly comes with a built-in safety feature to cutoff motors in an event of a crash. This scenario is detected by extreme roll or pitch angles. If you tilt the drone more than 45 degrees, it will automatically reset. To resolve this issue, keep the drone on a flat surface and turn on.

3. When trying to take off, the drone does not respond and blink both LEDs 3 times.

Keep the drone on a flat surface and retry.

4. One propeller is not rotating properly after a severe crash.

First, check if the propeller guard has loosened and is touching the propeller. You can resolve this issue by pushing the propeller guard downward.

 

If the issue persists, check whether the propeller has moved to the very bottom of the motor shaft. If this is the case, lift the propeller to the middle of the motor shaft.

 

Finally, snap on the propeller and ensure it rotates freely without any resistance. If it suddenly stops even after following the above two steps, the motor might be damaged. Follow the motor replacement process explained in the assembly guide to install the extra motor.
