Away907 02/01/2018
This is a great board, but i was unlucky to get it with defective gyro: 1. Pitch axis gyro getting almost 3 times more noise at 250hz than yaw and roll. This noise can not be handled by BF 3.2 dynamic filters alone: noise spikes causing motors to produce weird sounds, drone is shaking and going out of control. Had to add additional notch filter. But double filtering creates delay in control loop, resulting in propwash and oscillations. Only good for slow carefull flying. 2. roll gyro drifts a lot. It calibrates perfectly during controller startup, but after 1-2 minutes of flying drone starts rotating around roll axis with rate about 10 deg/sec, have to compensate it with the stick. 3. Some random glitches when doing a fast flip around pitch axis, it starts spinning around roll axis too. Sent some videos and betaflight log sceenshots to BG support, waiting for their response.
