Need help analyzing a crash

[dkemxr (Dave)]

Ah, OK. There is a photo of this craft in this thread.

Hex keeps flipping over on its back when taking off (RESOLVED)

OK, I tried some pics. The back view shows the red arms in front. From the same position I zoomed in to the controller (which is from mRO) and you can see their logo which points forward. This is exactly how I built 4 identical drones. Using PX4 firmware they all flew very well with a 0 degree setting. [drone_back_view] [pixhawk_orientation]

The FC was mounted backwards relative to the motor config. He used Yaw 180 FC orientation to fix it.
