The Jurca Gnatsum is a French homebuilt near scale replica aircraft based on the North American P-51 Mustang.[1]

Design & Development[edit]

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:-

Variants[edit]

One thought on “Cannabaceae”

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
