Design & Development

The Gnatsum (Mustang spelled backwards) is one of many wooden homebuilt designs from Romanian designer Marcel Jurca. Jurca, a Henschel Hs 129 pilot in World War II, expanded his warbird replica designs to include the Allied North American P-51 Mustang fighter. [2]

The Gnatsum is a low-wing, cantilever monoplane with an enclosed single-seat cockpit and manually retractable tailwheel landing gear based on that of the Jurca Sirocco. [3] Suitable for a number of engines around 200 hp (149 kW), plans for the Gnatsum are available as the 2/3 scale MJ-7 and the 3/4 scale MJ-77, as well as the MJ-70 full-size representation. All versions are constructed from wood with fabric covering, and manufacturing rights to the kit aircraft were acquired by Falconar Avia. [4] Plans for the MJ-77 are available from Avions Marcel Jurca. [5]

Some of the engines suitable for the MJ-7 Gnatsum series are:-
