The above weights for the Reduction Drive are for the engines that include the Diehl Accessory Case package, intake manifold, Slickignition system, oil cooler and the reduction drive unit.

An advantage of reduction drives is other than wood props may be used. Octane requirements will vary with compression ratio as will horsepower output. Great Plains engine "are not" certified aircraft engines. They can only be used in homebuilt aircraft that are certified in the "experimental category."
