The BD-8, a high performance aerobatic aircraft, was developed by BedeCorp in the late 1970’s. This plane was built to rival the Curtis Pitts biplane, which was a small, very agile plane that featured a low moment of inertia around the various axes. Mr. Bede sought to achieve the same qualities and advantages, but as a monoplane. The BD-8 had much lower drag than its biplane counterpart, which it gave it an edge in performing vertical maneuvers.

Since the BD-8 was very similar to the BD-4 in construction, it made this dynamic plane easy to assemble, utilizing the same bolted-together fuselage stringers. The aircraft could withstand +/- 12 g’s, and employed an asymmetrical airfoil that allowed for both positive and inverted flight aerobatics. The fuselage had a relatively large side area that permitted “knife edge” flight and the all-flying tail was linked to the aileron, enhancing the roll capabilities, by increasing the differential movement of the horizontal tail.

Two BD-8’s were produced in total and tested very well, but were never fine-tuned, causing its production to be halted. Its competitive design, however, has great potential and is prospected to be activated again in the future.
