ReDrives Inc. -
Raven Re Drives has been providing the ultralight and
light plane industry, 4 stroke engine alternatives for a
number of years now. They first entered the market with a "how to
manual" on converting the Geo Metro/Suzuki engine for aircraft
application. The manual takes you from what you need to purchase
at the wrecking yard, the computer wiring, starter, alternator, how to
lighten the engine on through to installation of the reduction
In addition to this Raven ReDrives also supplies
reduction drive kits and engine packages, tailored around the Geo/Suzuki
line of auto engines. These 4 stroke liquid cooled, overhead camshaft
engines have a proven track record of reliability in aircraft use. One
of the reasons is that the engine is designed to run at 3950 rpm @ 75
mph in the car - which is the same rpm used in aircraft application.
