Zenair Zenith

In his spare time, Heintz began to design and build his own aircraft, which he named the Zenith, anagram of Heintz. After a little more than a year’s work, the two-place low-wing Zenith was rolled out and successfully flown in 1969.  Soon after, detailed blueprints and construction manuals of the aircraft were drawn up and offered to the growing number of interested builders and flyers.
