I pickedup one of the Nakamichi N Racer Bit clones tonight at Wal Mart. 14 bucks...same frequency as my zap. Controller works great with the Zap. My 27 mhz Zap had crap for range. With the Naka controller it is at least doubled. I can run it down the length of my kitchen without so much as a shiver. With the Zap controller the car would stop after about 5 feet. I post this because I know some people are not comfortable with a sodering iron and this is a fairly cheap solution if you don;t want to change the antenna on the controller. Plus I find the Naka controller more comfortable to use.
