This 16-tooth motor gear is an RC-scale accessory built for direct use on motors that match a 0.5mm module and a 2.2mm motor tooth diameter. Constructed from 40Cr steel with a hardened black treatment, the gear focuses on wear resistance and consistent transmission in small-scale motor drive trains.
The gear uses a round-shaped motor hole and is secured with two set screws sized 3x3, which provide a simple clamping method for compatible motor shafts. Before fitting, check your motor's module and pinion diameter to confirm compatibility, as only motors matching these parameters should be used.
In tuning or maintenance, this gear serves as a straightforward replacement or spare that helps preserve mesh geometry and reduce premature tooth wear when paired with properly matched spur gears and motor setups. It is intended exclusively for RC models and model-grade motor assemblies.
