I may have to make a linkage and put the servo on the other side of the tranny. And then there is the linkage for the throttle and brake.......hmmmmm....
You could always use a Y-cable and twin servos for any of those functions. e.g. one servo per wheel for steering, and perhaps a mini-servo for the throttle and a regular one for the brake or something. Then the linkages are a piece of cake.
