The MFI BA-12 Sländan is a single seat ultralight of pod and high boom configuration and with a butterfly tail.
It is built from composite materials, with a square section beam formed in two halves supporting the engine well ahead of the wing leading edge and extending aft continuously to the tail.
On each side a forward leaning bracing strut runs from the lower rear cabin to the front wing spar.
The Sländan has a short, fixed, tricycle undercarriage with a steerable nosewheel; the mainwheels, fitted with brakes, are mounted on straight steel cantilever legs from the lower fuselage.
[1] The prototype Sländan was initially powered by a (21 kW (28 hp) König SD 570 4-cylinder two-stroke engine though there were plans to replace this with a Lotus Magnum 2.25 when this type became available.
