RE: Why should I use a PCM receiver
ozzieflier,
In your last post you made a very important comment that to me sheds a great deal of light on this issue. You stated that the plane "outside looped (about 3 times) into the ground". To begin with I don't see how a plane with the throttle cut could outside loop three, or even two times. Secondly the fact that it stayed in what we're all assuming is "lock out" for that long is EXTREMELY unlikely with out either MASSIVE interference or another problem like low (or no) voltage going to the RX.
I'm sure you checked things, but i would seriously have to call into question whether or not the RX was even receiving power (or adequate voltage).
Did you check the battery voltage after the crash?
Did you try wiggling all wires to check for shorts?
Did you do thorough checks on the power switch?
Was it the same switch on both planes?
Were you using a regulator?
When testing on the ground after the crash did you have to re-plug anything in?
Are you sure the switch was still in the on position after the crash (Don Szczur had his first Brio turn itself off in flight from vibration).
