you need to swap your reciver wires round on the reciever, you have them back to front to sort the drive problem.

if you are using an electonise switcher, when you turn it on, it fires the relays for a brief second and then sets back to a neutral position.

or if you mean it stays on, then you have wired it into the wrong side of the relay, you need to go into NO ( normally open ) not NC ( normally closed )

Hope this helps.
