This new gear set provides Mini 4WD racers with another setting option. It will give your machine a gear ratio of 3.7:1, which is faster than High-Speed Gear Set (Gear Ratio 4:1) and slower than Super Speed Gear Set (Gear Ratio 3.5:1).
The Universal Arm set is useful in a variety of Tamiya Construction and Robotics projects. The 3mm holes are spaced 5mm apart for use with other Tamiya Construction materials. Four arms are included.
