Hexsoon EDU 450 Frame Motor spin problem

Cube Autopilot
1

Hello everyone,

I recently started building a quadcopter using the Hexsoon EDU 450 frame with the Cube Orange Plus. I’m having some problems:

  1. Motor Speed Issues:
  • When I arm the drone, only Motor 1 (CCW) / Motor A spins, while the other three motors stay still.
  • When I increase the throttle to 15%, the other three motors start spinning, but they are much slower than Motor 1.

I’m using the 4.5.5 firmware on the Cube Orange Plus.

Any advice or help to fix these issues would be greatly appreciated. Thankyou
