Help with H9 Cub
 
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?

What receiver were you using?

A 127. I put another switch and battery in and it works fine. I was more upset about the hole in the covering more than anything. Now I just need to pick up another battery for my UCD.

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.

Thats possible, but it was a JR battery that matched the JR switch, and when you plug them together they only have two wires. If they were plugged up backwards then the wires would not match and would not do anything. I am pretty sure it was the battery pack.

What about the connection of the switch to the Rx? The switch itself could be bad, and shorted the battery when you turned it on. Can you test the switch with a volt meter?

It melted at the the battery conection. I just tossed it and installed a good one. I kept the broken parts so I could see if H9 would atleast replace those parts. I think I can use that Flag sticker to cover the hole that melted in the side of the fuse. On a side note, even the Cub reviewed in RC Report had a broken rudder.
