Ace / Aircraft Engineering Corp K-1 / Ace 200 / Ace 300
Keane K-1
The 1919 K-1 biplane was designed by Alexander Klemin (Professor of Aeronautical Engineering, NYU) and N W Dalton. The prototype had a Ford T motor. The K-1 featured four "self-aligning" I-struts and all-wood frame. The landing gear was fitted with a skid with the rear end turned down to act as a brake in landing.
Manufactured at the ACE Flying Field in New York City's Central Park, it was one of the first planes to be built on an assembly line, primitive as it was. Final assembly and flight tested at Central Park (Bethpage) Flying Field. Its engine was built in Queens. The aircraft performed well for its day, it was fully aerobatic and sold for $2500, eight were built. One made the national press when it landed on Clay St in Oakland CA as a publicity stunt on 1 December 1920.
Production model in front of a hangar at Central Park, Bethpage, L.I.
The 1920 version was modified with beefed-up struts, redesigned fuselage with enclosed motor, and folding wings. These sold for $3,000.
Circa 1920 the inventory and manufacturing rights to ACE K-1 were acquired by Horace Keane, (sales office) 280 Madison Ave, NYC, (plant) North Beach, Long Island NY. Photos of the plane appeared in some Keane ads.



In 1931 Ace produced two, with Salmson AD-9, N952Y c/n 1, and LeBlond 5D, N953Y c/n 2, registered as Ace 300 and 200 respectively. One located and restored in California 1955, N69097.
