Unfortunately this is all too common for the helimax gyro. I think I've made my point about their gyro, use it at your own risk or just buy a nice Futaba one that you know will work. I'll be getting the GY240 or something similar in the future. Heck, maybe I'll try the xheli.com gyros out. Did I mention though that the Axe 400 is a fantastic heli to fly? Very stable, very nice over all, just a really great and fun copter. J
