MicroHeli Front Shaft, Gear & Pulley Kit


This is an optional MicroHeli Front Shaft, Gear and Pulley Kit, and is intended for use with the Align T-REX 450XL and 450SE. The Front Shaft, Gear and Pulley Set is aimed at achieving true operations on the front gear drive assembly. With a bigger, stronger and high quality steel shaft, the new shaft can withstand larger forces making it is less susceptible to bending. This design is improved over stock shaft by eliminating the need of applying glue on the shafts. It also comes with a CNC Aluminum front pulley to eliminate the stripping of the stock plastic front pulley. The front Aluminum pulley fits perfectly on the new tail shaft and is held securely by set screws on the slot of the steel shaft. Plus, the blue CNC gear is made of super strong material and is CNC machined to guarantee roundness and wobble-free operations. This is a must have item for every T-REX owner.
