I have a spektrum 2.4 AR7000, was installed in a previous plane involved in a heavy crash, no impact obvious, can I install this in a new plane; if range test and function tests perform correctly. Are there any other tests that could be used to confirm.

Cheers

You may also try tapping on the reciever as you test each servo individually. If there is any glitches while doing this, the reciever may be damaged.

I would think if it binds,all functions work and range tests out it should be good to fly. If you have any doubts, send it in for a check-up . Just my .02

Thanks for that, I think to be 100% it's off for a check up.

Each to his own but the rx is probably the most critical component in the model and IMHO, any rx involved in a crash merits a trip to the service center....
