Hyperion Hardened Steel Pinion gears are the designed to put explosive performance in your 3D helicopter. The Pinion gears are machined from a special steel alloy and are hardened for ultimate strength and durability. During the manufacturing process, extremely tight tolerances are maintained so the pitch of the gear is precise. This means Hyperion Pinion gears run very quietly and efficiently. Compared to Steel, Brass or Aluminum gears wear out fast, causing degrade in performance due to the interface between the pinion and spur gears coming loose. The hardened Pinions are so tough that you can eliminate the need for spare gears in your toolbox. The Pinion gears are also strong enough to survive any insane power system that you choose to fit in your 3D helicopter.
