RE: Interesting problem ...input invited
Nope. I never had trouble when on 72mhz channel 40 with this plane. Now it's doing it on 2.4 ghz so that leads me to believe it's something inside the plane. Both the 72 and 2.4 receivers are wrapped in foam.
I performed an amp draw test last night and didn't see any irregularities. I guess the next step is to gut it and install different servos, switch, and battery.
