Tamiya 70156 Long Universal Arm Set

The Tamiya 70156 Long Universal Arm Set can be combined with other Tamiya products to construct crank systems, link systems, and structures for your robot or other project as illustrated in the instructions shown here.

This set includes four 41-hole arms with 3 mm holes spaced 5 mm apart. The arms can be cut to the desired length (each arm has regularly-spaced grooves that help to make a straight cut), and the holes can be modified to create longer slots for use in a cranking system. Also included is a set of screws and nuts for connecting the arms to each other and to your robot or other project.

For a shorter arm set that includes some other hardware, see the Tamiya 70143 Universal Arm Set.
