Plan file details

Mustfire. Radio control low wing multi aerobatic model, for .45 to .61 power. This design was later kitted by Frog in the UK. Quote: "RCM&E Kit Revierw No10. Frog Mustfire. Attractive 67-3/4 in span low wing multi aerobatic model. TO be honest, when we first saw Frog's kit for the Mustfire, our immediate mental reaction was to question the advisability of kitting a multi aerobatic design at least five years old. The Mustfire is a Swedish design, the creation of Jesper von Segebaden, and has been highly successful in Sweden. It has also been kilted in Germany. The first appearance of the design outside Sweden was at the 1962 World R/C Championships at RAF Kenley, where the model was used by Swedish team member Per Eliason, to place 15th. We relieved von Segebaden of reduced scale drawings which appeared in Aeromodeller December 1962 edition. Eliason also used the same Mustfire at the 1963 World Championships at Gent, Belgium where he managed to break the fuselage in two, when the model hit an officials' tent during a landing approach. The Mustfire spans 67-3/4 in, and has a generous wing area of 790 sq in. Wing section is a semi-symmetrical 12 percent thick airfoil. The shape and size of the machine, with its large wing, bulky fuselage, inset ailerons and provision for tailwheel type undercarriage, tend to identify this machine with the daddy of 'em all, the good old Astro Hog (oz4756) and it was this similarity that let us to our initial reaction to this kitting project. Subsequent experience has proven just how wrong you can be. The kit contains a vast number of die cut components, all crisply cut in the sample received. Fuselage sides are cut in one piece, and the full depth wing spars are cut and notched ready for use. The builder is offered the choice of tricycle or tailwheel type undercarriage, steerable noseleg and main undercarriage being provided, together with other hardware including nylon control horns, aileron bell-cranks, and a fine moulded cockpit canopy. The wing structure consists of a main spar, a rear spar, and a false aileron spar, each being full depth types. Each spar is notched to accept the wing ribs and is shaped with a surplus spar fillet on the bottom..." Update 09/05/2018: added review of the Frog kit, from RCM&E, May 1967, thanks to RFJ.
