Bad GPS navigation

Long battery leads and inductance

I'm building a Bormatec Maja. Like many UAVs it's a pusher with the motor at the back and I want to put the battery right at the front for balance. I Googled for some ready made battery extension leads and didn't find any. But I did find this discuss

Auto takeoff and crash x2

Can anyone help me find the cause of the only two crashes I've had with my FPV Raptor and APM 2.5.

I've done a dozen or so auto take offs successfully, but two of them resulted in crashes. Actually in both cases I recognized things weren't going well
