FT Flyer Unpredictable Nose Dives??

[ofiesens2]

Forgive me if I am wrong, I know next to nothing about what I am talking about, but could the motor possibly be drawing too many amps for the ESC? I feel this might cause some sort of glitch in the receiver.

The ESC would be extremely hot if that was the case, but it is certainly a possibility...

servo for elevator may not be able to hold against torque on elevator surface or you have a stripped gear in the elevator servo. as the gear turns and runs across the stripped gear, the servo slips and the elevator deflects down causing the plan to pitch down. that is my theory which is mine. .
