As Light Sport Aircraft become more popular, so too will the desire to learn more about maintaining one of the most common engines used in these designs, the Rotax four-strokes.

When new aircraft from two very different designers, in this case Randy Schlitter and Richard VanGrunsven, surface with considerable similarities, consensus about basic design tenets must be blowing in the wind. Certainly Light Sport regs do constrain performance considerations, but human factors are more up for grabs, and thats where one or another design can truly shine; by Marc Cook.
