Select builds from the 25 model set. There are instructions for 12 of the models, pictures for the rest. Lots of good parts in this set although orange plastic parts get brittle with age. Building a thrust bearing using the spacers is neat. Overall, the set is a little hampered by relying on belts (elastic bands) for transmission, which are not able to transmit as much torque as gears.
