Hi. I recently picked up a used Duratrax GP car to fiddle around with, and I'm going to let my girlfriend use it. Now, thing is it was working fine for awhile, but now while the engine is running, I get very bad servo glitching, to the point I can't drive the car. It's the crappy stock RTR radio and reciever. I believe it's a 27mhz AM unit. I've tried insulating all the wires ect. but it is no help. Would getting a cheap 75mhz AM unit help, or should I get an FM unit. Keep in mind, this is just for my girlfriend to bash around with, and I am not spending a great deal of money on it. I have a Cen Matrix Buggy with an MX-3, and I really like it, but I can't get it locally. Thanks guys.
