I’ve recently changed all the ESC’s on my quad to SimonK ones to improve it’s handling and responsiveness. But now every time it takes off it rapidly starts precessing and inevitably crashes within a few seconds. I’ve tried tuning it using the extended tuning panel in Mission Planner with no success.
I’ve had a look in the log file and the gyros and accelerometers seem to be giving the correct readings.
Has anyone seen anything like this before when changing to SimonK ECU’s. What could cause it and can be fixed by tuning parameters alone?
The firmware is : ArduCopter V3.1.5 (3c57e771)
Here’s a link to a video showing the behaviour:
Thanks in advance
