After a crash today the controller is acting very strange. Sometimes the heli lifts off at zero throttle and as you advance the throttle it slows down and at full throttle the helicopter experiences full throttle .. its like an electrical problem .. with no 'stop'

All components look fine, tailrotor works fine, batteries have been changed for new ones but problem persists.

Has anyone heard of this problem?

Do you think this is the result of the switch issue?
