Been flyin my chopper for about week now, and starting to get a little more adventurous. I'm having a problem now though that when I give it a little more throttle to get it a little higher in the air, I can see the light on the gyro pack go from green to red and then the tail wants to swing around to the right at great speed. Thinking that the gyro can't handle the torque at that throttle level and cuts out? anyone know what else could be the problem?
