That looks pretty sweet. On 18 cells, it should be a beast! Try charging your batteries and see what happens. they could need a few cycles. The glitch could be one or more of several things. The antenna could be touching metal, a capacitor could have come loose on the controller. It could be weak transmitter batteries or a bad servo or receiver or crystal. I would start with the simle things like location of the electronics and go from there.
