Steve,

For what it is worth, I feel your pain. I trashed a brand new one two weeks ago on flight 3 for the aircraft.

One thing that has not been mentioned here is a question as to the orientation of the TX antenna. Was it pointing up or out. Out would be bad. Especially if you were pointing it at the plane. I also set up my Futaba 2.4 recievers with one antenna running verticle.

I would also suggest fastening the reciever antenni a little different. Perhaps a peice of nyrod clamped as you have it with the antenna run through it. Or at least make sure you have not compressed the coax to the point of breaking.

Just for grins - I noticed you had tail brace wires. I would confirm they were vibration free. I have had only one glitch with my 2.4 Futaba's and I related it to metal to metal vibration created by worn connections on my tail brace wires.

Good luck finding the cause and with the rebuild.
