RE: Do you replace your RX / FMA copilot after a crash ?
Hook a servo to the AR6200 RX and connect to to a battery pack.
Now move the servo around, while lightly tapping on the case.
Do this with each channel.
If operation remains smooth, in spite of your tapping, and the case shows no damage, you should be fine.

As for the Co-Pilot, I'd remove that set of "training wheels" asap.
