[6] The Miniplane is a conventional single-bay biplane with staggered wings of unequal span braced with N-struts and wires.

The fuselage and the tail fin are of a conventional truss design constructed of welded steel tube and covered in fabric,[1][2][7][8] and the wing spars and ribs are made from spruce and also fabric-covered.

This model featured more cockpit room for larger pilots, a new airfoil and re-drawn plans to aid construction.

[11] The Miniplane 2000 incorporates several modifications to the original design, including a slightly longer and wider fuselage to accommodate larger pilots,[11][12] adding bracing struts to reinforce the horizontal stabilizer,[11] and changing the airfoil section[13] and angles of incidence of the wings.

[11][14] In August 1959, Tom Messick flew a Miniplane on a 4,200-mile (6,700-km) round trip to attend the EAA Fly-in at Rockford, Illinois and was awarded a trophy for flying the longest distance to the event.
