Reduction Drive System for the Type 1 VW!


Reduction Drive Parts
The NEW Series 3 Reduction Drive is available in drive ratios from 1.6:1 up to 2.5:1. Props used vary from 72 inch x 40 inch pitch up to 96 inch x 56 inch pitch. It greatly improves the take off and climb performance of any high drag VW powered aircraft that needs more thrust.

On a 2180cc engine with a 1.6:1 drive and a 72 inch prop, you will see about 350 lbs. of thrust. On a 2.0:1 drive and an 84 inch prop will pull about 450 lbs. of thrust. You get the idea! (A direct drive VW with a 62 inch prop will pull about 215 lbs. of thrust.)

The Series 3 Redrive System has the following features:
3 or 4 each 10mm belts
Bolt on - no welding or machining required
Standard 75mm Rotax bolt pattern
Steel crankshaft sprocket with timing marks at 0 and 30 degrees
New idler arm with Easy Belt Tensioning System
Crankshaft oil seal
Includes all necessary installation hardware
Raises prop 5.5 inches from the center of the crankshaft
Installation instructions included
Weighs 17.8 lbs. Can use a light weight flywheel!
