Bryan Aircraft Inc.

The conversion of a Schreder HP-18 glider into a Jet Glider, equipped with two Jetcat P300 engines, is the work of Chris Esselstyn, an American homebuilder based in Waukesha, Wisconsin.

The HP-18 is a standard class metal glider. This is the 14th plane of Dick (Richard) Schreder. His first flight took place in 1975. It was marketed to American homebuilders as a kit.
