Design and development edit
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 11.2 m (36.7 ft) 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 edit
In August 2011 there were two GA-1s registered in the US with the Federal Aviation Administration. US-registered aircraft are in the Experimental - Racing/Exhibition category.[4]
