[3] Blacker's design changes included adding a +2 degree of dihedral to the upper wing, redesign of the horizontal stabilizer, installation of a diagonal brace at Stations 2 and 3, a change to the fuselage truss assembly, strengthening of the control column support, and a ball-bearing arrangement.

[4][5] The design is a single-seat biplane of conventional configuration, with staggered, single-bay equal-span wings braced with N-struts.

[13][14][15][16] Blacker put the prototype's incomplete fuselage as on display at EAA's 1958 fly-in.

The prototype EAA Biplane work, along with the other facets of Project Schoolflight, resulted in the award of the Mechanix Illustrated trophy for "Outstanding Achievement in Home-Built Aircraft".

[17] The completed prototype EAA Biplane was first publicly shown at the 1961 Rockford, Illinois Fly-In.
