The aircraft is now supplied as plans for amateur construction by Manna Aviation.

Falconar indicates that it incorporates a larger cockpit, simplified fittings, shoulder harnesses and aerodynamic improvements to improve stall characteristics over the Jodel design.

[5] Hans Teijgeler of Jodel.com says that the F12A varies from the D11 by using a new wing design, with new simplified spar and rib design and the dihedral point moved inboard, allowing the outer portion to fold for ground transport or storage, but at the cost of added weight, plus the option of a third seat.

Teijgeler also notes that the F12 uses much larger and heavier engines with higher fuel consumption.

Just a fact to take into account"[6] The F12A features a cantilever low-wing, two-seats-in-side-by-side configuration, with an optional third seat, an enclosed cockpit that is 44 in (112 cm) wide, fixed conventional landing gear, or optionally tricycle landing gear, and a single engine in tractor configuration.
