Wow, what a dissertation. After wading through that one I can only say a couple of things. If it is electrical, it will fail eventually and all the checks on the ground cant stop it. Yes you will find the obvious ones, however, the very nature of electrical failures prevent you from finding them all.

Just because you chose to buy JR does not mean in any way shape form or fashion that you are immune to electrical, receiver, or servo failures. Last season we had a H9 Cap with JR gear less than 2 weeks old that had a servo (8411) failure on the right aileron that resulted in the aileron going to full down deflection (one of the rudder servos went belly up 1 month later). Things were interesting for a couple laps till the pilot was sure he could land it, and he came on in without incident. I myself have landed several planes with this condition, I have also burned in a few that were just not savable. My Edge went in last year after the left elevator servo went to full up deflection while inverted. The amp gave out and that was all she wrote. In this case, with an elevator half at full deflection (62 deg.) you, myself, or chip Hyde will not bring this plane home in one piece, it just ain't happening.

This thread is getting off the original topic so I will go no further....
