yep, just had the same thing happen to me. I got everthing hooked up, and it looked great. I followed the programming, but the sucker would not arm to run. I had thought that maybe it was just the trim on th radio, but it was electronically set too high to arm. as soon as I reset the throttle end points, the arming beeps occurred and i was good to go. I am now a happy camper.
