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.

[1] The two occupants were provided with dual controls and were accommodated beneath a long blister canopy.

[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.

RFB built a total of 22 Multoplans and abandoned a further three when production was discontinued in 1961.
