Variations
Some notable variations of the aircraft include:
Fuel: The standard location of the fuel tank is forward of the instrument panel. Some builders have moved it to the leading edges of the wings. By creating a sealed leading edge tank, the fuel is moved away from the pilot for better crash survivability with the added benefit of more than doubling the fuel capacity.
Fuselage: The plans state that a builder can increase the width and/or height of the bulkheads in an effort to make the fuselage more hospitable for larger pilots.
Engines: The standard engine for the design is the four-stroke, 1/2 VW engine. An engine literally made by cutting the block of a standard four cylinder VW engine in half. After machining and welding, the remaining two cylinder engine is light and powerful. Alternative engines include the more powerful but heavier four cylinder VW engine, the two-stroke Rotax 447, even the McCulloch 0-100-1 drone engine popular with the early gyrocopter builders.

Famous quotes containing the word variations:
“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)
