i've noticed that the first generation bits can use the 7 tooth pinion gear (the white one lol). i've noticed that bits which operate on the old controller can use it while the new ones cannot. to tell if yours is old or new, look at the charging station. the old charging station is kinda grey see thru and matches the grey see thru on the controller. however, the new ones have charging stations like clones. i.e. they are jet black. has anyone else noticed this? cuz my friend who had an old one can use a 7 tooth while i couldnt on a new one. i was pissed off for so long until i put the 7 tooth into my old one and to my surprise it worked. btw i used the initial d set and he had the honda accord wagon. it seems to me like the old ones have wider chassis while the new ones have narrower ones which is why the old charging station is wider.
