The Rhein Flugzeugbau RW 3 Multoplan is a two-seat light pusher configuration aircraft that was produced in small numbers by Rhein Flugzeugbau GmbH between 1958 and 1961.
The prototype RW 3 Multoplan was designed by Hanno Fischer who founded Rhein-West-Flug Fischer in 1955 in order to test the aerodynamic principles that he propounded. These were first tested in the Fibo 2a light aircraft. This was followed by the first RW 3A Multoplan D-EJAS which was a tandem two-seat light aircraft of mixed construction with a high aspect ratio wing, retractable tricycle undercarriage and a T-tail. The 65 h.p. Porsche 678/0 engine was buried in the centre fuselage and drove a pusher propeller mounted in a vertical slot between the fin and rudder. [1] The two occupants were provided with dual controls and were accommodated beneath a long blister canopy. [2] A second RW 3A-V2 was built and tested. [3]
Fischer granted a production licence to Rhein Flugzeugbau GmbH (RFB) who built an initial batch of Multoplans at their factory at Krefeld-Uerdingen. The first production aircraft was flown on 8 February 1958 and this and all subsequent machines were designated RW 3.P75 to identify the Porsche 75 h.p. 678/4 engine which was fitted. RFB built a total of 22 Multoplans and abandoned a further three when production was discontinued in 1961. One further example was built by an amateur constructor. [4]
RFB also built two examples of a higher-powered version, the RW 3C-90 Passat and on these and all other RW 3s, they offered optional wingtip extension panels which enabled the Multoplan to be flown as a power-assisted sailplane. [5] The extensions increased the span from 34 ft 9 ins to 50 ft 6 in. [6]
The Multoplan was mainly operated by private pilot owners. Two examples remained operational on the German civil aircraft register in 2009 and two aircraft were exhibited in German aviation museums including D-EIFF displayed in the Deutsches Technikmuseum in the centre of Berlin. [7]

The Klemm Kl 107 was a two-seat light aircraft developed in Germany in 1940. It was a conventional low-wing cantilever monoplane of wooden construction with fixed tailwheel undercarriage. Wartime production totalled only five prototypes and some 20 production machines before the Klemm factory was destroyed by Allied bombing. Following World War II and the lifting of aviation restrictions on Germany, production recommenced in 1955 with a modernised version, the Kl 107B, of which Klemm built a small series before selling all rights to the design to Bölkow. This firm further revised the design and built it as the Kl 107C before using it as the basis for their own Bo 207.

The RFB X-113 Aerofoil Boat was an experimental ground effect vehicle intended to work over water. It was one of three such aircraft designed by Alexander Lippisch in the 1960s and early 1970s. The X-113 first flew in 1970; only one was built.
The RFB X-114 was a ground-effect craft, designed chiefly to operate over water but capable of flight at higher altitudes where required, carrying five or six passengers or freight along coasts and capable of surveillance duties. One was evaluated by the German military in the late 1970s, but no orders followed.
