Sounds to me like it's not set up good. When you did this, was the engine closed and the throttle and trim switch down completely on the tx and servo closed with no mixing when you attached it?
I did all of the above with the exception that I had 20% of expo dialled in on the throttle. Positioning the servo arm/pushrod as Sinergy suggested and with a bit of expo added solved the problem and now I am good to go. Funny how sometimes the little things can be the most baffleing.....thanks all.
