The quarter scale FFG Prag Fg227 was powered by 6 ILO 2 stroke engines rated at 21hp each. It was a ¼ scale BV.238 built by students at Prag under the direction of Dipl.Ing. Ludwig Karch.
A quarter-scale testbed called the FGP 227, registered as BQ+UZ, was deemed necessary to test the aerodynamics and water handling.
Intended to allow flight tests to commence from the manufacturers airfield, the FGP 227 refused to take-off from the grass airfield.
The aircraft was dismantled and transported to Erprobungsstelle See, Travemünde (E-Stelle – flying boat testing station). 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.
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. The FGP 227 was again repaired after which the aircraft flew several more times. By this time construction and testing of the BV 238 had started, so no useful data was gleaned from the programme.
