Yesterday I downed the REX450sa. 430L. 35amp align speed control, gy401. Got home surveyed the damage and rebuilt the frame. When I plug up the batt. the gyro blinks but no servo response at all and no setting beeps from ESC aside from the escalating tone when plugged in. Any ideas as to what electronics are gone? I'm thinkin ESC cause the lower frame was bent bad so it probably took a good shock. All help and responses are appreciated.

I wish I still flew!!!

Remove the ESC lead from the receiver and power the rest of the electronics up and see if they work .

At the end of the day , it gets dark .
