Help, can't control 2 cars at once?
 

Hi, I'm new here and I just brought two zip-zap r/c. I brought a Mazda Savanna (charges fine BTW) and a 1997 Toyota, the Fast and the Furious edition. They work fine if I try using one at a time, but when I try to use both, the Supra doesn't work. Can you tell me how to fix this problem? I know that I can adjust the frequency on the Mazda, but can I adjust in a way so the Supra and the Mazda can race at one time? Please no flame about buying a 1st generation, if that was what I brought. Thanks in advance :D

What frequency is the Toyota? 27MHz or 49 MHz?

The Supra is 27 mhz, and the Mazda is also 27 but with 6 selectable Frequency.

I think having two 27 MHz cars is causing your trouble. Even though the Mazda has 6 different frequencies-I don't think you can run them at the same time. Try to return the Supra for another ZipZap in the 49 MHz frequency.
