The Delrin Helical Main Gear w/ Auto-Rotation Hub set is specifically designed for improvements in stability, durability and overall performance on the Spyder 300i helicopter.
The Helical Main Gear w/ Auto-Rotation Hub set is CNC machined from Delrin and Aluminum material. It is directly replaced straight main gear. With proper helical pinion design, the Delrin Helical Main Gear w/ Auto-Rotation Hub set brings more silent operation, strength and efficiency than the straight main gear; because it is diagonally positioned, the teeth in a helical gear train engage a little at a time rather than the entire face at once. In addition, the angled teeth also engage more gradually than do spur gear teeth, making them smoother and quieter, and at the same time producing axial thrust on the shaft for much more strength.
