Ie The Hatz CB-1, Hatz Classic and the Hatz Bantam

The Hatz CB-1

The original Hatz CB1 was designed by John Hatz in 1968 as a 4/5 scale version of the RNF Waco biplane. John couldn’t afford a Waco, so decided to build his own. He designed the CB1 to fly behind a 90 to 100 horsepower engine, with the cylinders exposed like a J-3 Cub.

Hatz Classic

The Hatz Classic is larger cosmetic redesign of the Hatz CB-1. Billy Dawson, of Texas, took the Hatz and rounded it off, stretched out the fuselage and gear to make it more reminiscent of a classic WACO. The result won Grand-Champion at Oshkosh and a company named Makelan Corp began marketing plans and components for the aircraft. The WACO of course is powered with a radial engine, but the Hatz Classic uses the Lycoming 0-320

Hatz Bantam

The Bantam is a interesting concept and even if it does not look so from the outside it might be the most radical redesign in this group. Much lighter then the other and fitted with the light and nice sounding Jabiry 6-cyl 3300 this should make a nice flying aircraft. Fits into the LSA concept as well. A work in progress since right now there is only a prototype.
