REVCO MOD0.5 HARDENED STEEL PINION GEAR, 3.5MM BORE
Note: The new Main Drive Gear is precision CNC-machined (manufactured by RevCo for KDE Direct) from Nylatron Type
66 Polyamide, an excellent material for polymer gears and the perfect match for an extremely strong, smooth running, and
durable power transmission. The gear is composed of 150 teeth, utilizing the metric MOD0.5 tooth profile standard for the
stock TREX 450 series helicopters. Through months of testing, the gear has been optimized to include numerous design
features for optimum performance, including:
(1) The tooth involute profile has been optimized through numerous design iterations for increased tooth engagement and
strength, providing an incredibly quiet and durable gear for a MOD0.5 power train.
(2) Weight was reduced through FEA optimizations of the machining pattern to significantly reduce weight, while
maintaining full strength of a solid-gear profile.
(3) The self-lubricating properties of the Type 66 Polyamide material provides exceptional wear and noise properties,
providing a gear that can withstand the harsh nature of hardcore 3D flight.
