This is an optional Lynx Heli 78 Tooth Ultra Main Gear Hub. Lynx has redesigned the T-REX 150 Main Gear Hub to support the Lynx CNC Main Gear. This option is dedicated to pilots who need a super precise and reinforced CNC Main gear to keep weight as low as possible, while not needing the autorotation system. The result will be smooth power and with heavy duty specifications.

Lynx spent much time optimizing the design, followed by heavy testing, to achieve the required strength and resistance, with a final design without compromise.
