My brand-new X-EC Diversion seems to loose the controller signal out at about 40 ft line-of-sight distance. I know this is not normal as the specs are 300 ft. The batteries are fresh, the plane's batteries well charged, the antenna is fully extended. The plane's antenna is hanging free and I didn't cut it or anything. The problem occured in two different flying fields so interference is ruled out. (other planes worked fine at both places too). It flies well inside a 40 ft circle or if I walk to follow it around. Otherwise, outside of 40ft it starts "spastic" motor fluctuations and gets out of control.

Any ideas on this problem?

Also- I plan to call Megatech tomorrow - any experience with thier support?
