Hey Claude, I'm glad to hear it came back in 1 piece.
Man, I almost had you beat. I tried to fly mine last week but suffered a fuel restriction problem from a kinked line buried back in the fuse. Its since been replaced and works again. with the size of this model, you're a brave man to fly it in primer!
I did get a few slow taxi tests in an found my nose steering a bit sensitive so the expo might need to go up a bit. I had heard a few reports of reflex needed in the wings so mine are set at 3/16 up with +/- 1.5" travel at 25% expo. I'm using Hitec 5625's on the ailerons, 5245's on the rudders, 225's on the steering, retract valve and brake valve, and a 625MG on the speed brake. I've also cut down the aileron throw to 70% of the recommended values in the manual.
If you're using an unregulated 6.0V pack, it could be causing the glitches. Sometimes the voltage can start out significantly higher than 6.0 and some servos just don't like it... I'm sticking to a 4.8V 1300 mAh pack. The ECU supplied with your motor should be pretty good with respect to EMI generation.
Hopefully we can compare notes later this week!
