This is an optional Compass Model 127 Tooth Helical Cut Main Gear, and is intended for use with the Compass Model 7HV and Chronos 700 helicopters. This main gear is machined from delrin for durability, with helical cut teeth for reduced noise and a smoother operating gear box. It is recommended that you drop one tooth on the pinion gear when using this main gear to compensate for the taller gear ratio.
