I just got my MT2 on Christmas. I'm happy all except for two things, my radio ( Impact II ), and the brakes. The radio, works about 40ft. away from me, and I've only ran about 12 tanks or so through( New Batteries ). I always turn off my radio and the reciever on the car whem I'm done to. Also, yesterday my car locked up, and we fixed it. The brakes had been working since. Now they don't work and we adjusted them to. Can anyone give me some pointers?
