I don't think it is the Superbee kill switch, because I loose all power to steering and brake. Including engine kill. I thought it was the on/off switch on the MTXL. I sprayed it with some CRC Quick Dry Electronic Cleaner and it made my run last a little longer.(20min) before total loss of all power. I jiggle the on/off switch button and then power restores. No loose connections(wires) on the switch. Do you think if I contact Horizon Hobby, they will send me out a replacement one at no charge? I only have 3 tanks of gas run thru my rig. Thanks
