The Czech Flugtechnische Fertigungsgemeinschaft Prag (FGP) was engaged to build a quarter-scale test aircraft.
[2] The FGP 227 was a faithful, approximately quarter-scale model of the proposed design, having a long, narrow hull with a high-mounted wing and conventional tail.
Power was supplied by six 15.7 kW (21 hp) ILO F 12/400 air-cooled two-stroke engines driving three bladed propellers, mounted along the wings.
[3] During transport French prisoners of war loading the wing onto flat-bed trucks allowed it to fall from a crane causing damage which was not repaired until September 1944.
[1] Flight tests commenced in September 1944 as soon as the repairs were completed, but all six engines stopped due to fuel starvation soon after take-off, resulting in a heavy landing on the water.
