Hi!!! I just got this radio and put it in a TT Raptor heli. I have the receiver and battery mounted in the fromt of the heli with about a 1/8th piece of foam between each piece. I ran a tank of gas in the heli and no problems. Started the second tank and the servos started chattering every now and then. Got so we couldn't fly anymore....at one time was hovering and all of a sudden slammed into the ground.

In thoughts would be much appreciated!!!
Thank You

From your description, it sounds like you don't have enough foam insulation between the heli and your components. The receiver and battery pack should have about 1/2 inch of foam wrapped around them. When you secure them to the heli, you don't want to compress the foam. The heli's vibrations can easily get to the components inside the receiver and cause problems.
