Saab Tunnan J-29E/F



The Saab Tunnan was an unusually shaped jet with surprisingly good performance. The first production version of the J29 which was nicknamed "Flygande Tunnan (Flying Barrel)", was the "J-29A". A total of 224 were built from 1951 to 1954, and entered service with the Swedish Air Force in 1952. The J-29A was powered by the RM2 Ghost with 2,270 kilograms (5,000 pounds) thrust, Trim tabs were added, as well as dive brakes. The dive brakes were mounted on the fuselage ahead of the main landing gear doors. The J-29A was followed by the "J-29B", which was fitted with extra fuel tanks in the wings, increasing its fuel capacity by 50%. It also was fitted with stores pylons for bombs and rockets, allowing it to be used in the attack role. For this reason it was also referred to as the "A-29B".

The initial flight of the J-29B was on 11 March 1953, and 332 were built from 1953 to 1955. The type set a world speed record of 977.35 KPH (607.05 MPH) over a 500 kilometer (310 mile) closed-circuit course in 1954. SAAB engineers continued to refine the wing design to improve the aircraft "critical Mach number", resulting in a new wing with a "dogtooth" leading edge. This wing was used on a new Tunnan variant, the "J-29E/F", with the prototype flying on 3 December 1953. 29 J-29E/Fs were built in 1955. The new wing was also refitted to S-29C reconnaissance aircraft, with no change in designation. The last variant of the Tunnan was the "J-29F", which featured the afterburning Ghost engine that had been evaluated on the single J-29D and the dogtooth wing developed for the J-29E/F. The prototype performed its first flight on 20 March 1954, and demonstrated greatly improved take-off and climb characteristics.

The Mibo Jets J-29 Tunnan faithfully recreates the J-29E/F version at a scale of 4.8:1 which makes for an impressive sized model with a wing span of 2.291 meters and a fuselage length of 2.13 meters. The all up weight of the model is approximately 14 to 16 kilos depending on how it is fitted out. The model is designed to use 10 to 12 kg thrust turbines and has plenty of room for the installation of your engine and accessories. The Mibo J-29E/F incorporates a perfect scale outline with an excellent level of detail including panel lines, rivets and hatches. The model is fully composite construction using glass, airex and Kevlar sandwich made under vaccum. This allows for an extremely light yet rigid model. The kit is highly preassembled with formers and fittings installed. The kit is furnished complete with canopy, hardware, instructions and a construction photo CD ROM.

Landing gear is available by separate order from MIBO, as are a number of accessories such as pylons and ordinance, with more under development.

An unusual subject, and a great flying model, the MIBO J-29E/F will provide you with many enjoyable flights whether for serious scale competition or jet flying with your friends. Dare we say it’s a “barrel of fun”
