The Celair GA-1 Celstar is a South African mid-wing, single-seat, aerobatic glider that was designed by Pieter Celliers and produced by his company, Celair (Pty) Limited. Design and development The GA-1 was especially intended for flying competitive glider aerobatics and the resulting airframe was designed to Joint Aviation Requirements 22 standards and stressed to 10 g. The aircraft is made from a combination of fibreglass and aramid. Its span wing employs a Wortmann FX-71-L-150/25 airfoil. The ailerons are full-span and mass-balanced. Dive brakes are used for approach control. At least eight were produced, with two exported to Switzerland and six to the United States.
