I have a Pixhawk Clone in my Telemaster that am currently trying to tune. I seem to have noise in my servos when I activate a flight mode other than MANUAL. It seems that the noise is particularly strong on the roll/x axis. After looking at the logs, it seems that X axis gryo from IMU2 seems to be noisy. What is the acceptable amount of noise from a gyro? SHould I try to filter this out? WHy are there two IMUs? Can the noisy one be turned off or is this not recommended? I have attached a log from my plane sitting still on the ground so you can see what I am talking about. The noise does contribute to about 15us of roll control, constantly.
Any help would be appreciated.
