RANS S-19

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.

Around the Patch

Those who plan to build an aircraft from a kit would do well to visit the factory and get to know not only the owners but also the operation.

RANS manufacturing is diversified to weather the ups and downs of the market, and the company knows what works and sticks to it.
