Overview

The Graal is a rigid self-launching one-seat glider conforming to French and FAI ultralight rules.
By its look, feel and performance it is very close to a 15 meter class glider. The Graal differs only by its ultralight construction. The engine gives it ease of use and a per flight cost dreamed of by every sailplane pilot.
