i’ve recently build a small quadcopter to experience the Pixhawk autopilot.
in QGC all is set to go but on takeoff the quad flips, not possible to steer anyway.
when props detached only functions working is throttle, yaw pitch and rudder does nothing.
in QGC all works fine

i’m using SUMD with Graupner MX20

any ideas as i am pretty new to pixhawk?

@timkk,
This is not a Pixhawk hardware problem.
You most likely have a tuning/programming issue.
What version of ArduCopter are you using so that I can move your post to the correct ArduCopter firmware sub forum?
Also, please proved tlogs and/or dataflash logs to help troubleshoot your issue.
