Hi guys!! Just a very quick question if I may?

Bought several HL tanks and converted to S&S, but only have the one S&S Tx, so cannot "play" tanks to full effect (with sons/ dad / wife). Thought I'd have a go at converting one of the stock Tx's using a S&S Tx board, but there are THREE sockets on the new board and FOUR on the old one. What have I missed (yeah I know...a plug...doh!!)[8D]

Any advice (other than stop being tight and buy the complete S&S conversion kit next time..huh!!??)

Cheers, and hope you all have a good weekend.
