codykrr, you can buy nicad batteries at walmart with a charger. energizer has some pretty nice ones, but they may be expensive. how are your servos acting? sluggish, or jittery? mine seem to work fine until i start the car. the carb opens up all the way with out me even touching it, then they just stop working all together. how many tanks have you put through your car? mine is brand new only 7 tanks so far. its my second day owning it.
