| Like many RotorWay owners, I decided to discard the stock RotorWay chain drive and replaced it with the Pro-Drive cog belt system. It's less complex and reduces weight by 20 lb.'s over the RotorWay chain drive. It also allows better air flow in the engine compartment which translates into better cooling. | |
The first thing to do in mounting the drive components is level the air frame using the square tubes as the reference point. I simply used blocks of wood under the skid tubes to shim the airframe level. The picture at right shows the square tubes at 0.0 degrees. |

Prior to installing the main drive sprocket, I took it to a machine shop to have it drilled and mounted to the hub. My drill press won't accommodate a part as large as the main drive sprocket. The bolts are a close tolerance fit and require a letter D drill bit to drill the holes. I didn't want to drill these holes using my hand drill. To install the main cog drive sprocket, the rotor shaft had to raised. Notice the blocks of wood clamped to the rotor shaft to hold it up while the sprocket is slipped on below. Raising the rotor shaft took some effort. But once I got it up and clamped, the sprocket slipped on easy. My father sent me the Flying Maige cap. |

| Once the main drive sprocket is mounted it must be checked for level. You can see it turned out perfect. |  |
| This is the main drive sprocket mounted with the bolts safety wired. The safety spacer tube is clamped in place around the drive shaft. |  |
