Im probably gonna go buy my first mini R/C car this weekend...I think I decided on the Zip Zap at Radio Shack. I've heard some negative things about the controllers being hard to operate due to tiny buttons. I was wondering if I buy a 27mhz car will my controller for my full sized Radio Shack R/C car operate the little Zip Zap??? I realize the Zip Zap controller will still be needed for recharging the car.
