(...) Hi Max, Well, I could use up to 3 of the old style 9v motors, or 1 geared 4.5v motor, or various pneumatic engines - perhaps a limit on the number of cylinders ;-). Are you going to consider classes for different power plants as well as the (...) (21 years ago, 16-Jun-03, to lugnet.technic, FTX)
