Are you looking to reverse with the relay? If so, you can wire two relays into an H-Bridge or get a dedicated reversing relay. The 3.7 control from the toy would drive transistors as in Franks diagram and these would feed 12v into the reversing relay coils.
Here's a reversing relay for a winch. Replace the MOM toggle switch with two transistors that provide switched 12v to the relay. You would hook the drains of the transistors to the relay.
