When to Replace

Installation Tips

1. Power off & remove battery before any work.

2. Photograph current wiring for easy reference.

3. Swap one connector at a time (motors/servos/LEDs/receiver).

4. Ensure plugs are fully seated and polarity is correct.

5. After install, re-calibrate gyro/level on a flat surface.

6. Verify 3D/6G mode switch works before first flight.

7. Perform a short hover test in a clear, wind-free area.

Note: X450 transmitters are available in different modes (Mode 1/Mode 2). This board works with either; set your transmitter correctly after installation.
