DETAILS: The Fibo-II-a (FiBo 2a) for Fischer-Boretzki) was one of the first post war light aircraft to appear in W. Germany. It was designed by Mr. Hans (Hanno) Fischer and built by his Rhein-West-Flug-Fischer & Company (RWF) and first flown during 1953. The aircraft already had several features of later Fischer designs such as the RW-3 and used a so-called slotted propeller installed behind the cockpit. The sole Fibo-II-a was powered by one 30hp Zündapp (DKW) modified motorcycle engine.
