The F9A design was introduced in 1965 and both the F9A and F10A were supplied as kits or as plans for amateur construction by Falconar.
[5] Hans Teijgeler of Jodel.com says that the F9A varies from the D9 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.
Just a fact to take into account"[6] The F9A features a cantilever low-wing, a single seat enclosed cockpit that is 21 in (53 cm) wide, fixed conventional landing gear and a single engine in tractor configuration.
[1] The F9A and F10A are made from wood, with the flying surfaces covered in doped aircraft fabric.
Construction time from the supplied kit is estimated as 700 hours.
