The side-by-side seating was in an open cockpit just ahead of the strut-mounted inline engine.
A horizontal stabilizer and elevator ran between twin fins with rudders, one at the end of each boom.
General Aircraft proposed the Cagnet as a basic trainer.
It was tested as a Flying Observation post trainer by the Royal School of Army Co-operation from February through June 1940 (with military serial number W7646).
The engine was a 90 hp (67 kW) Blackburn Cirrus Minor, which gave a cruising speed of 100 mph (160 km/h).
