Why is the VW so Popular?

From our beginning, Great Plains Aircraft has been at the forefront of producing the highest quality parts for use on VW air-cooled Sport Aircraft power plants. Great Plains Aircraft is committed to producing the highest quality and safest VW derived aero power plants and VW conversion parts in the marketplace, and we believe we have the safest conversion available.

At Great Plains Aircraft, we have learned a great deal about automotive technology and its applications to aircraft in the last 26+ years. If you read through past issues of aviation journals such as Sport Aviation, Custom Planes, etc., you will get a brief history of the many automotive engines that have been introduced to the sport aircraft marketplace . . . only to fail. Why did they fail? Set aside the fact that many of the automotive engines introduced were one of a kind. Discard the fact that several of the prototype engines were destroyed. Disregard the fact that some of the producers of these engine designers did not have the personal commitment or financial backing to stay and develop the product. And do not forget about the fact that some of these engines had horrific failures.

The single leading cause of Engine Failure in the marketplace is the lack of a product (airframe) for the engine.

WHAT MAKES THE VW SO POPULAR?

ADVANTAGE VW. The air-cooled VW engine has 50+ aircraft worldwide that have been designed specifically around this dependable engine. These aircraft were designed with the VW engine as the power plant of choice. In addition, the VW air-cooled engine conversion has been retrofitted to existing popular aircraft such as the Kit Fox, Avid Flyer, Kolb, and Rans - check our web site for listings.

HISTORY. The VW air-cooled engine has been used in sport aircraft since the late 1940s. It has a history! Its strengths and weaknesses are well known and documented. FAMILIARITY. The majority of the baby boomer generation has had experience with VW engines at some point in their life.

POPULARITY. The VW engine has more sport aircraft designed around it than any other automotive engine conversion.

PARTS AVAILABILITY. Because of the engines continued popularity, the user is not locked into a companies success. In other words, when using a VW conversion, if the company you purchase it from fails or goes out of business, you are not stuck with a useless piece of metal. i.e., HAPI, Mosler, TEC, Barker, Monnett Experimental, INAV, Ltd., etc.

WEIGHT. A VW conversion will typically weigh between 145 - 190 pounds and deliver between 50 - 103 takeoff horsepower (includes Front Drive, Flywheel and Reduction Drive). FRONT DRIVE. This standard aircraft configuration has no gear reduction, no high engine RPMs: for this front drive. It is a simple fact of life - the faster it turns, the shorter the engine life. Most comparable automotive engines in the same general market place as the dependable VW turn 4500 to 6500 RPM to produce their usable horsepower through their reduction drive and weigh considerably more. The Front Drive uses a wooden prop only and turns counter clockwise from the cockpit in a tractor configuration.

FLYWHEEL DRIVE. The Flywheel Drive engine is the least expensive engine configuration sold. An aluminum prop hub is bolted to a custom flywheel that is a little larger than a stock VW flywheel. The starter is mounted on top of the engine, laying over the engine case. It utilizes a 40 amp belt driven alternator, mechanical fuel pump and optional dual electronic ignition. This is also the lightest VW conversion sold with the fore mentioned options, weighing in at 158 lbs. for a 2180cc engine.

REDUCTION DRIVE. Driven off the pulley end of the engine. The Reduction Drive offsets the centerline from the prop vertically 5.5 inches. Available in 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 59 inch pitch. It greatly improves the take off and climb performance of any high drag VW powered aircraft that needs more thrust.

COST. No where in the sport aviation marketplace can you purchase a NEW 70-103 HP engine, with dual ignition, for $5861.
