"Carr Twin" 1/2 VW Plans
The "Carr Twin" Plans offer plans for both the cut case and full case versions.
ADVANTAGES OF THE VW ENGINE:
Parts are low cost and available throughout the world.
Lightweight: The crankcase is made of magnesium, 13 lighter than aluminum with excellent heat transfer qualities. The heads are aluminum. An 87 pound, 35hp engine is hard to beat!
Air-cooled: With both cylinders exposed to direct air stream.
Crankshaft RPM corrects for direct mounting of propellor (no need to gear down or belt drive.)
A four-stroke engine with generous bearing diameter means long life, extra reliability, and low fuel consumption.
Can be used in tractor or pusher properllor configuration.
A fun project for the mechanical craftsman!
