RcPilotJAE,

Actually, the sloppy wiring comment gave me another theory as to why the plane took about 30 sec or so before the interference got so bad that I totally lost it. My wiring in
general wasn't sloppy, but with one possible exception. The wires in the fuselage that go from the receiver to the aileron servos in the wings...I always left loose to make it easier to connect to the aileron servos wires from the wing. This hadn't been a problem for 6 months because the ignition battery was near the front of the fuse well separated from any receiver component. However, when I moved the ignition battery to the middle of the fuselage, the aileron servo wires going from the receiver were well within reach of actually touching the battery. So my theory is, at takeoff, these wires were separated enough from the ignition battery that there was not a problem. However, after I take off I usually (and I did in this case) do a half rolling circle. The rolling circle allowed these wires to be shifted in such a way that they either became very close or began to actually touch the battery, and that is when the inteference overwhelmed my transmitter signal and the receiver went into failsafe.
