Came real close!! I grounded the heli until the problem was found or a different RX/TX system was tried. Worked with the thing an entire day, systemtically, took the blades off and ran it (low RPM!!) and bingo the RXs kicked a low voltage light. Thats is when I knew I was on to it. The biggest thing to remember is GROUND the heli if it is glitching, it is is one potentially lethal thing if you loose it!
