Description
This HobbyStar Pinion Adapter allows you to mount a pinion gear with a 5.0mm bore onto a 3.2mm (1/8") motor shaft. It's good to have at least one of these pinion adapters on hand, even more so if you have quite a few RC vehicles in your fleet with different motor shaft sizes.
Includes: 1 - 5mm to 3.2mm pinion adapter.
