AT700-MDGM1-HDS
Overview
The new Slant Main Drive Gear Heavy-Duty series is precision CNC-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 for the ALIGN T-Rex 700/800 and alternate-brand series R/C helicopters. The gear is composed of 112 teeth, utilizing the metric MOD1.0 tooth standard for incredible strength.
