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.[1]

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.[1]

The aircraft is made from a combination of fibreglass and aramid. Its {{convert|11.2|m|ft|1|abbr=on}} 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.[1][2]

At least eight were produced, with two exported to Switzerland and six to the United States.[3]

Operational history

In August 2011 there were two GA-1s registered in the USA with the Federal Aviation Administration. US-registered aircraft are in the Experimental - Racing/Exhibition category.[4]
