I built a trifecta frame with APM micro.I calibrated accelerometer and seems level in MP. During take of 1 motor delays to begin rotation until half throttle. I first thought that it is an ESC Calibration problem but the difficulty is the delayed motor changes everytime. Moreover we can see that even the frame is levelled channel outputs are different. What can be the problem ?
I added a video explains the problem:
First red signed motor delayed to start and then problems is shown on the tail
