Glitches ARE a common occurance on the AXE CP using the stock 72mhz FM radio, interference can come from many outdoor sources, lightpoles, high-tension power lines, etc. I had a BAD glitch in the begining of December, I was hovering at about 15 ft, when the radio glitched into what seemed like IDLE-UP mode. The throttle was below mid-stick, which cause my AXE CP to POWER-SLAM itself into the driveway (wasn't a pretty sight). Several other within this forum have had glitches without even touching the TX that cause a good amount of damage to there heli.
Some of us have replaced the stock radio system with something else, I myself upgraded to a DX7, and it's been smooth flying ever since.
