Actually each of the parts I've ordered have come with an Allen wrench, but I also ordered a 0.050" driver. Everything seems to be the same size, and everything I've messed with is threaded (no nuts except for the wheels).did you get a tool set for these tiny ones?




for the long distance driving they do, it may be better to keep them the standard gears to avoid binding all the time.

Wonder which one is yours?![]()
What unit is that?
