My octocopter with APM1 and oilpan running 2.7.3 software has a quite alarming power surge in the motors when yawing. Yawing either way results in a an audible surge of the motors and quite rapid height gain. The surge stops and the rate of altitude gain slows if you hold the yaw command on.
I had hoped these two threads were going to spread some light on the issue but they seemed to stop as things started to get interesting.
Has anyone else experienced this problem and if so what was their solution?
