I am getting some bad interference with a 27% extra and da50 engine, brand new. Weird part is that with the engine off I get no glitches at all. I have over a foot between all the engine components and receiver. I even used all plastic rods to go into the engine box. At first I had the antenna inside, then moved it outside the airplane with a little bit better but I still get glitches. It gets worse as engine power is increased.

Checked all the linkages and all are tight. I am using pull-pull and the wires are not crossed and not chafing anywhere. Without the engine running I have a perfect range check. Engine running I have half the range check before the glitches begin, rudder and throttle glitches. All the radio gear and servos are brand new, with a new engine. I am trying everything with this thing and not getting any great results. I have been running gas for awhile and never had any problems like this before.

More ideas would be great, thanks.
