Designed with Park Flyers in mind

These gear drives are real "efficiency-boosters" for the smaller 280-size electric motors that are popular with today's Park Flyer airplanes. They maximize battery capacity for longer flight times, while allowing you to utilize bigger props as well.

Nylon gear/brass pinion combination produces minimum noise and smoother mesh with less maintenance.
T400 models feature open, machined-aluminum frames — GD600 frames and sealed S280 cases are strong, fiber-reinforced nylon.
S280 and T400 models available in bushing sport (Std.) and ball bearing (BB) competition models.
Props with 1/4" dia. center hole require Prop Adapter (available separately).
