RE: receiver setup
I use hitec servos and a programmer so that I don't need the matchboxes etc. Here is how I have my setup. As you can see this greatly simplifies everything. I use y's to the rudder servos and to the ailerons in the wing so that there's only 1 extension being plugged in to the receiver. If you loose 1 receiver (which is the least likely possible failure of everything in the plane) you will still have control over half of the plane, aileron/elevator which you can still land with. I've seen it done 2 times in one meet. The cause wasn't a failed receiver though, it was a bad battery connection where it plugged into the receiver, loose connection. The plane was landed fine both times.
