This GPM aftermarket Delrin motor gear is produced for Kyosho Mini Inferno owners who need a direct replacement motor gear. The part is supplied as a single 13T unit intended for the motor pinion position on Mini Inferno electric RC models, and it is described here strictly as an RC-scale accessory.
The Delrin material reduces friction between mating gears and tends to run quieter compared with harder plastics, which helps during setup checks and testing runs. When replacing the motor gear, pay attention to gear mesh and shaft alignment, verify free rotation by hand, and confirm the motor spins smoothly before powering the model for a full run.
This item supports routine maintenance and basic tuning where swapping a worn stock gear for a like-for-like Delrin 13T can restore quiet operation and predictable gear engagement on Mini Inferno setups.
