Is this an ESC problem

[jbaur]

Hello. I have been flying my super cub LP without incidence for about a month now. The other day I did a hard nose over on landing and cracked the motor mount. I replaced it and the plane would only get about 60 percent throttle and make a weird droning noise. I thought maybe I damaged the motor so I went and replaced all the components. Prop Shaft with Hardware, Spinner, Cowl, Complete Gearbox, and the Motor with Pinion Cub. I still only get about 60 percent throttle with a strange droning noise. (and the droning noise is only present when i attempt throttle above 60 percent. It sounds normal below that level) Everything is assembled correctly as well. I examined the ESC/Rx and noticed the black motor lead had come loose. I re-solderd it back in place but it didn't fix the problem. Whats wrong? Do I need to replace the ESC? Thanks in advance. Josh.

Maybe your prop is un balanced.
Did you check that the fire wall did not get cracked or became loose from the accident??

I have installed a new prop and taken it off the firewall and I get the same problem. On a freshly charged battery I get a constant 11.6v off the motor leads. Is this normal?
