I started assembly of my Cub this eveing. When I plugged the battery in and turned it on, it just started smoking. The battery pack got very hot and melted a hole in the plane covering and unsoldered its own conections on the battery and split the covering. I hooked it up with the brown wire to the brown wire. Its a two wire conection. Did I hook it up wrong? Or was it a bad battery pack. I have the switch hooked in the a Futaba reciever. Does anyone have any ideas?
That sounds like a classic dead short or reversed connection. You said brown wire----Futaba only uses white, black and red, the battery connections being red and black. Could be that if you have a switch intended for JR, which has a connector that doesn't have the little side pin the Futaba connectors have, that one of the connectors from the switch to the Rx, or the switch to the battery, was plugged in backwards.
Of course, it could have been a bad battery pack, I suppose.
