Several people have asked me where to connect the leads from their li-ion pack to the tx board.
I hope the two pics make it all clear.

You can just spot the polarity through the hot glue blob. :lol:
Hope this is of use to someone.

Hi,borybo,you need to remove the pcboard from the transmitter,turn it over,and locate the 2 places where the original battery connector is soldered to the board.Make sure you have the red in the same place,and the black too.
Then you unsolder the original connecter wire.I cut a normal servo extension cord in half,and soldered the wires from the female half to the board.The bit of hot glue is just to make sure the wires don't get pulled out.Solder the male half of the extension cord onto your li-ion pack,and you can plug it in.
You may also need to make a lead to connect to your charger.Hope that helps.
