The Kelley’s Aero Service Z-STOL was designed, engineered & structurally analyzed by Zivko Aeronautics to Part 23 standards. The Z-STOL wing is a custom design airfoil by John Roncz.
Z-STOL is a rugged two seat side by side high wing aircraft with a 44″ wide cabin. Flight controls are push-pull tubes for elevator, aileron & flaps, and cable for rudder. Fuselage & tail surface are 4130 tubing and fabric covered. The 35′ span wing is all aluminum. Wing area is 175 sq ft, with slotted flaps, frisk style ailerons, Horner wing tips, and two 12 gallon aluminum fuel tanks. The aluminum main landing gear and wheel/brakes are from Grove Aircraft. The engine is a spec-built Lycon O-200 experimental making ~120+ hp. The cowling, wing tips, instrument panel, floor boards & baggage area are carbon fiber composite. Z-STOL is an amateur-built experimental that fits in the light sport category.

I have built the tooling & the flying prototype of Z-STOL aircraft & taken it as far as I can for a one man operation; I’m looking for the right person with the facilities & employees in place to take Z-STOL into production. If you’re interested in buying the tooling & manufacturing rights for Z-STOL aircraft e-mail me for further details at email@example.com. Price is $170,000.00 (serious inquires only). Thanks, Kelley
