REVISED: 3/7/09


Douglas Kaddy, West Groton CT.

1934 = 1pOhwM; 20hp Ace motorcycle engine; span: 20'0" v: 30. Parasol ultralight was limited to flights around a local pasture because, Kaddy explained, "That kind of operation in 1934 in this part of the country was highly illegal."


Everett E David, Detroit MI.

  Kadiak KC-1 [R11312] (Dan Shumaker coll)
  Kadiak KC-1 [NR11312] (Frank Rezich coll)

KC-1 Speedster 1931 = 1pOB; 55hp Velie M-5; range: 550. Repowered with 90hp Lambert; span: 19'10" length: 16'8" v: 155/132/52. POP: 1 [NR11312=N41C]. David was 25 years old when he built KC-1 and taught himself to fly in it. Sold in 1939, damaged in a Texas tornado c.1961, and rebuilt. Relicensed in 1951, it was seen still active in California 1977. "Kadiak" is Inuit spelling for the Kodiak bear of Alaska.


Kaess Aircraft Engr Co, NJ.

CL-1 1926 = 3pOMF; 70hp Anzani 6A3; span: 36'8" length: 22'0". Custom-built, designed by "Belanco" (Bellanca?) for a Karl Mueller. Destroyed in a fatal crash at Lake Hopatcong NJ on 7/29/27 (p: Earl Beers).


Daniel (or Donald?) Kaiser, Chicago IL.

Triplane 1912 = The only textual description found was a "double biplane with paired wings, and two sets of landing wheels fore and aft." Reportedly had a metal-covered fuselage; built but never flown. An enigma here with two subsequent (1926) aircraft registrations that could be from the same person, and with two possible mispellings, but which is the correct one remains to be solved. Conversely, by some very odd coincidence, Daniel could be three different persons living in the Lake Michigan area. To be considered, as well, is that DoC registrations scribes had a very cavalier attitude toward spelling, names in particular.

Kaiser, Kayser

Dan Kaiser or Kayser, Racine WI.

Canuck 1926 = 2pOB; 90hp Curtiss OX-5. Intention seemingly was to duplicate Canadian Curtiss JN-4s as new manufacture, but the motivation behind that is unknown, and curious at best. Racine Journal reported that "Kayser" left for Milwaukee in 1929 to become manager of Curtiss-Wright Airport "and took his factory with him." SEE previous entry.

Kaiser, Kiser

Daniel Kiser or Kaiser, Milwaukee WI.

Airliner 1926 = 7pCB; 300hp Hisso; span: 30'0" length: 47'0" (?). POP: 1 [NC2865] c/n 21. Sold to a party in Kenosha in 1928 and its path faded. There was also a Packard-powered "Kiser" registered, [C931N] c/n 53, but no supporting data were found. SEE previous entries.

Could this be the Charles Munsall plane used for barnstroming? {— John M Jarratt 5/20/02)

(Henry J) Kaiser-(Lloyd) Stearman Aircraft Co, Oakland CA.

Y-2 Aircar 1946 = 4pClwM; 220hp Lycoming R-680 pusher; load: 2200# v: 150/130/40 range: 600. Postwar attempt by industrialist Kaiser to revive a modernized, air-scoopless Stearman-Hammond failed in the face of financial hurdles. POP: 1 [NX91090].


No location.

c.1928 = No specs or data.

I have a picture of a 2pOB, vintage of 1928, no visible reg. On the back is the notation "Kalec Biplane," although the hen-scratch could be "It" instead of a "K". I suspect that it was taken in Michigan by Don Wigton, from whom the print came. Not a bad looking little job with either an Anzani or a stationary LeRhone. (— John W Underwood)

  Kimball (Jean-Pierre Lauwers coll)

1908 = 1pOH; 50hp Aero & Marine; rotors: 4'0". Empty wt: 112#, gross wt: 600#. Kimball had the bizarre belief that a large number of small rotors would be lighter than one large rotor of the same total disk area. Thus his helicopter had no less than 20 rotors covering an area of 320 sqft, belt-driven by the single motor. Drive system problems developed, not surprisingly, and the framelike machine never left the ground. It was later destroyed in a fire.

1910 = 1pO ornithopter-type, curved shoulder-wings on either side; twin props driven by a motor mounted behind the pilot.

Beetle 1929 = No data.

New York #1 1909 = 1pOB; 50hp 4-cyl auto engine driving eight 4'0", four-blade, pusher props by way of a wire-rope belt. A previous model, with six propellers, never got off the ground at its much-publicized unveiling at Morris Park. This second design, sponsored by the New York Aero Club, was damaged slightly at its christening on 5/18/09, "as the propellers would not all work," but it eventually gained success to some degree, only to crash two months later.

  Kimball Tailless (National Archives)

Designed and built by Kimbell, who bought a book on aerodynamics and taught hiself welding, the ship's stability and performance was praised by a "Major Pine." Kimbell, as well, finally made his solo flight, then gave up aviation for marriage and sold his creation [13970]. Reportedly was written off c.1938 when it nosed over after an "illegal flight," whatever that was.

X 1927 = 1pOB/OBF; 1250hp Packard X-2775; span: 29'10" length: 26'9" v: 323. A private seaplane venture by engine manufacturer Kirkham and then-Navy Lt Al Williams, with support by Packard Motors, for the Schneider Trophy Race prize of $100,000. All-wood construction, powered by two 625hp Packard V-1500s mounted in a common crankcase to form an impressive four-bank, 24-cylinder, X-shape motor—hence the model designation. Originally on twin pontoons, money ran out during the testing stage and the plane never made it to the starting gate at Venice, Italy. It was converted to wheels, however, and later set an unofficial world speed record of 322.6 mph.

  Cycloid Theory (clip: ibid.)
  More Cycloid Theory (clip: ibid.)

Kirsten 1934 = Odd design project—as a "cycloidal flying machine"—by notable professor of aero engineering Kirsten, one of several with revolving airfoil-shaped blades replacing wings and stablizer to offer faster airspeed and slower landings, as well as hover. Based on the wing-rotation employed by birds, in level flight cycloidal blades each make a half-turn for every revolution, giving horizontal top blades four times the lift per unit of a fixed wing, bottom blades would be vertical and provide thrust while moving backwards in the path of flight. Theory: If a bottom blade is moving backward at 100 mph, the top blade is moving forward at 200 mph with respect to the air—speed of the blades in their orbit plus speed of the machine that supports them. The attached clips help in explaining this graphically.

Knight Twister

1928: Vernon W Payne, Cicero IL. Name evolved from a pun, "A good knight's work." 1938: Ended production after failing to secure financing, but there were a few experimental prototypes built after this date, and sales of plans continued. c.1947: 5047 Miami St, St Louis MO. c.1960: Kit and plans sales, Long Beach CA.

1934 = 1pOB; 50hp Anzani; span: 15'0". POP: 1.

About that Anzani, it's possible that Payne considered it, but it was never used. The prototype [13661] originally had a 45hp Salmson. It was later rebuilt and much improved around a 50-hp Douglas, which was an air-cooled conversion of the Ford Model A engine. (— John W Underwood 10/17/07)

SEE Victor-Knoll.

(My grandfather) returned from a short vacation and saw that the crew had painted the popular cartoon, Felix the Cat, on the door—the port side had doors, the starboard side had only painted doors (also with Felix the Cat). He was very upset, but the cats stayed on the plane. Three KN-1s were sold to Mexico, and rumors have it that there are two alongside the road in a terrible state of decay south of Rosa Beach. Colors were blue for the fuselage and orange for the wings and horizontal stabilizer. Most all of the KN-1 documents that remained are in the Smithsonian, donated by his eldest son (my uncle).

Young Ho Koun, Roosevelt Field, NYC.

  Kouns-Craft [37156]

Kouns-Craft 1939 = 1pOlwM; 40hp Continental A-40. A piteous journey of a Chinese cook into the realm of flight featured his odd creation, registered as "Koun's Aircraft - Dirigible - Helicopter (Pats. Pending)." Built mainly from parts of other aircraft, the wing was built by Koun and a friend and fitted with a large airfoil-shaped bin on each wing, to be filled with helium before flights, assumably to help the lifting qualities. Wings had outrigger wheels to keep the drooping tips from dragging on the ground. The "helicopter" part was its engine, which was mounted on a gimbel so that it could swivel up and down. During a run-up test, it broke its tethers and, pilotless, led inventor Koun and his crew on a wild chase around the field, miraculously missing other aircraft, until the engine quit from a fuel blockage. It was reportedly damaged in the episode and never did fly. The CAA refused to issue an Experimental Certificate, even though they did assign registration [37156], and Koun's dream, along with $6,000 and five years of work, sadly went down the drain.

Lawrence Brown, Albin Peterson, based on Brown-Mercury C-2. POP: 1 prototype [X71E]. The brainchild of Larry Brown, it proved disappointing in that it was barely able to clear the mountains on its shakedown cruise, which was Ogden's honeymoon. Later equipped with a single 330hp J6-9 and a hopper and used by the Vremsak Ag operation until totaled in a crash while dusting bean fields at Yuba City in 1936. (— John W Underwood)

Photoplane 1925 = 1pOmwM; 30hp Lawrance A-2; span: 30'2" length: 18'3" load: 200# v: 70/x/20. Built entirely from parts of other planes; wings were modified from a de Havilland DH-9. As the name implies, it was designed for aerial photography with a large-format camera attached under the fuselage. Its first flight ended as a crash-landing into a chicken-house after take-off (p: Clair K Rodgers). Following a patch-up, the second flight ended in a wing failure during landing, and another crash.

"If you are in trouble anywhere in the world, an airplane can fly over and drop flowers, but a helicopter can land and save your life." — Igor Sikorsky, 1947
