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.
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. Suitable for a number of engines around , 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.
