Founded in 1961 as Rotorway Aircraft by B.J. Schramm as a kit helicopter manufacturing company.
In 1990, the company was acquired by John Netherwood and became Rotorway International.
The Exec series had a fully enclosed structure and cockpit with an elastomeric rotor head. The Exec 90 introduced a new landing gear, additional tail boom structural modifications and increased diameter shaft. A new pair of windows were added just above the pilot and passenger heads and the fiberglass access panels were split.
Since 1994, a new and improved model was made, the Exec 162F. This model has 150 horsepower with a 162 cubic inch powerplant. Also part of the design is an asymmetrical main rotor blade, a fully automated digital engine control system (FADEC) that provides complete redundancy.
Buford John Schramm died April 28, 2004. He was posthumously inducted into the EAA Homebuilder's Hall of Fame in 2006.
