For me I draw the line at physical damage such as you described for reuse of the Rx regardless of any range test. Damage such as that often results in two things either a cracked ceramic filter or a cracked circuit board/trace that may be intermittent .


Its important to understand the so called self righting tendencies of some airplanes is perhaps only in the first 15 or so degrees of roll. And will certainly not save an airplane if the signal is lost. If signal is lost that airplane is going to crash.
