This is an optional KDE Direct Mod .07 Pitch, 115 Tooth Main Drive Gear, and is intended for use with ALIGN T-REX 700N/700N E-Conversion series helicopters, as well as T-REX 550E and 600E series helicopters with the addition of the T700 Main Gear Case (AT550/600-MGC). This Main Drive Gear is precision machined from a proprietary Nylatron MoS2-Filled Type 66 Polyamide, one of the best materials available today for polymer gears and the perfect match for an extremely strong, smooth running, and durable power transmission. The gear is composed of 164 teeth, utilizing the metric MOD0.7 tooth profile that is standard for the stock TREX 700N, 600E/ESP, and 550E series helicopters. Through months of testing, the gear has been optimized to include numerous design features for optimum performance, including:
Weight: 48 grams
- 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 MOD0.7 power train.
- Weight was reduced through FEA optimizations of the machining pattern to significantly reduce weight, while maintaining full strength of a solid-gear profile.
- The self-lubricating properties of the proprietary MoS2-Filled Type 66 Polyamide material provides exceptional wear and noise properties, providing a gear that can withstand the harsh nature of hardcore 3D flight.
