The HUDY 294027 aluminium ULTRA-LIGHT pinion is a purpose-built R/C scale gear engineered to reduce rotating mass while retaining the strength needed for reliable drivetrain operation. Machined from 7075 T6 aluminium and given a hard coated surface, the pinion combines low inertial weight with improved wear resistance suited to both electric and nitro R/C setups.
Precision tooth shaping is produced on a dedicated gear machine to ensure ultra-true running and minimal vibration under load. Fine internal threading simplifies attachment to compatible motor pinion hubs, and each unit is etched with the tooth count for quick identification during setup and tuning.
This pinion functions as a tuning component: changing tooth count affects final drive ratio, acceleration, and top speed characteristics. Use it in combinations with your spur gear to find the desired balance between acceleration and top-end performance on track or practice sessions.
For hobbyists seeking reduced rotating mass without sacrificing durability, this HUDY pinion offers a precise, hard coated aluminium option for drivetrain tuning on R/C cars.
