I have a new 32-bit alexmos controller from Viacopter. IMU is calibrated and moves logically on the GUI. However when i connect everything, the roll motor doesn't respond to the RC at all and just oscillates.
The pitch motor follows the RC, but near the end of the travel it starts shaking violently I am using the default factory settings & behavior is the same with and without camera. Here is a video
I don't think it's a motor problem because swapping the roll and pitch motor cables transfers the problem to the pitch motor.
Then probably basic settings are wrong (motor inverted status, IMU orientation, Power settings etc.) or it needs to be better PID tuned. It could be so many thing it is really impossible to say what is wrong.
