Himax Stick Mount Gearbox comes with an aluminum dual ball bearings gearbox frame, 3 different gear ratios (4.4:1, 5.3:1, 6.6:1), a harden output drive shaft, and a 3.0 mm Aluminum Prop Adaptor to take APC props. It has the same 10.0 x 10.0 mm mounting box as GWS EPS-300/350 and EPS-400 Gear Drives. The built-in cooling fin on the aluminum gearbox frame keeps the motor cooler. This gearbox can take most of those 20.0 diameter brushless motors. The pinion gears have 2.0 mm bore. |
