Eagle [1] DW-1 Eagle

Deliveries of Eagle Aircraft’s new ag-¬plane, manufactured by Bellanca, were planned to begin in October 1979. Designed from advanced glider technology, which en¬hances fuel efficiency, the Eagle was cer-tificated with 220 and 240 hp Continen¬tals and 275 and 350 hp Jacobs (all radi¬als); certification was pending with the 300¬hp Lycoming opposed powerplant.

Wood wings and steel tube fuselage, all Dacron-covered; spoilers on top surface of lower wings for more precise control at spray speed (65mph).

An agreement with Bellanca Aircraft Corporation of June 1979 was for Bellanca to manufacture Eagle on its behalf. Eagle production lasted until the early 1980s.

EAA Super Acro-Sport

This further development of the Acro-Sport is intended for unlimited international-class aerobatic competition. Though basically similar in appearance to its counterpart, the Super Acro-Sport takes advantage of a more powerful engine turning a fixed-pitch prop, an improved roll rate and inverted flight capabilities. Its two wings have almost sym¬metrical airfoil sections. Also added was a trim tab on the starboard elevator and a servo tab on the port side.

EAA Acro-Sport

This biplane was designed by EAA President Paul Poberezny who wanted to come up with a plane that could be used in high school industrial arts programs and Civil Air Patrol groups as an educational tool. The first flew in January 1972, less than 12 months after the design was started. The Acro-Sport can be fabricated with tools normally found in a high-school shop. It is built with steel tube covered by fabric and 100- to 200-hp engines.

EAA A-1 Biplane

In 1955, the EAA decided to develop a single-seat sport biplane as a service to its members. The prototype was built as a classroom project by students of St.Rita’s High School in Chicago. It flew for the first time on 10 June 1960. The E.A.A. Biplane was designed in response to many requests from members of the American Experimental Aircraft Association for a single seater sports biplane of simple yet rugged construction. The fuselage consists of a welded chrome-moly steel tube frame, to which are fitted plywood formers and wooden stringers, the whole being fabric covered apart from the aluminium coaming panels. Both upper and lower wings have solid spruce spars and built-up wooden ribs, and are internally and externally wire braced. The leading edge to the front spar is aluminium covered, the remainder being fabric covered. Interplane and centre section struts are made of streamline steel tube. A 9.5 Imp. gallon fuel tank is fitted behind the firewall. The empennage, like the fuselage, is built up of welded steel tube and is fabric covered and externally braced. The ailerons which are installed on the lower wing only, are operated by means of push rods, while the elevator and rudder are cable operated. The main undercarriage is built up of steel tube with bungee cords for shock absorption.
