Sonnich, are you sure your receiver is cooked? You may have just shorted the battery cells and of course the recvr. would not function after that. Try new battery. My charging switch is set up so when switch is off you plug into charge receptical. This is direct connection to battery, recvr. is off and isolated. Also if I try to insert the plug in reverse polarity nothing will happen as they use the standard three wire connector with only two wires, plus and minus ,run to the center pin and one outside pin. This way a backward connection does nothing. I hope it's just the battery .Contact PJP Jets about the wing fences,maybe they have a pattern you can use from their small Hawk kit. DB
