MTL it works
Your idea for a 2 speed using the Gaogeng race win transmitter and receiver works.My order from toys east came in and toys east.My Taiyo mini cooper was a DOA car so I put the Race win electonics in the car.What i did instead of trying to solder on the board is i used the wiring that was already on the board and conected it to the correct spots on the car.The steering rotor are the same size so I just stuck it in place of the Taiyo steering rotor.So i only had 4 wires to solder.I cut the center mounting peg in the body of teh MINI cooper body down to 1 inch long screwed the receiver in that post with front mounting hole.Then i hot glued the back of the receiver to the back inside the car.The car perfrom okay with alklines batteries in the car because you get 3 volts.The first gear is kind of slow second gear turbo works best in a straight line.If i added one mor battery to the car it would be faster.So pat your self on the back for coming up with idea.
