The Tamiya Universal Arm Set can be used to make crank systems, link systems, and structures for your robot. The 41-hole arms consist of 3 mm holes spaced 5 mm apart making the arm set compatible with many Tamiya products and sets.
This set includes four 33-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. Four L-shaped brackets are included in the set for mounting axles or for use as structural support. Also included are twelve spacers at 5 mm, 10 mm, and 15 mm lengths, eight plastic nuts, and a metal screw and nut set.
