First thing I noticed with mine glitching was the antenna wire was actually tied in a loose knot around the landing gear beside the body of the heli... this knot to me basically shortened the antenna wire from its original length to a lenght of about 1 inch.

I untied the knot, ran the wire so it was not wrapped around the skids etc... and haven't had a glitch in the reciever since....pictured below is what I did to mine.

hope it helps ....
