My car is a 45mhz 2-spd and my friend has two 1-spd’s at 27 and 45mhz. I can get his 27mhz to run off my controller, but not his 45mhz. I know about the ABC switch in the back. I took a look inside the controller and everything looked fine. I haven’t dropped it or anything, it just stopped working. I think that the crystal in the controller just went poo. I have to wait till I get another 4-band controller to see if the car is ok. Any more info is greatly appreciated. Thanks…
