Condor Aircraft Condor

Condor II

The Condor II is a single seat single engined high wing mono¬plane with conventional three axis control. Wing has unswept leading and trailing edges, and constant chord; cruciform tall. Pitch control by elevator on tail; yaw control by fully flying rudder; roll control by one third span spoilerons; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from above by kingpost and cables, from below by cables; wing profile; single¬ surface. Undercarriage has three wheels in tricycle formation; torsion bar suspension on nosewheel. No ground steering. No brakes. Aluminium¬ tube framework, with optional pod. Engine mounted below wing driving pusher propeller.
All rigging wires are stainless steel with a vinyl coating and double swaging, and the aluminium tubing is ano¬dized clear and ‘covered with stabilised Dacron’.
Lift off and landing speeds are quoted as 20 24 mph (32 39 kph) and 20 25 mph (32¬40kph) respectively.
Options include floats, ballistically de¬ployed parachute, strobe, pod and electric start; normally, starting is by recoil, with an in flight restart facility. Price in 1982 of $5245.
Condor Aircraft describe the Condor III as a beefed up version of the Condor II, designed for heavier payloads, and accordingly the company quotes a much higher maximum take off weight for this side by side two seater with single centre stick.
The Condor III+2 is a two-seat version. Dual stick and rudder three-axis controls, dual throttle.

Condor Shoestring K-10

The original Shoestring was designed by Rod Kriemendahl and was built in Van Nuys, California, by Carl and Vince Ast, with help. Shoestring is a Formula One airplane. Its 19-foot wing has an aspect ratio of over five. All Formula One racers are required to have a minimum of 66 square feet of wing area, but Rivets and Shoestring stand alone with their tapered, longish wings. Apparently, the better overall efficiency of the higher aspect ratio wings is well worth the slight increase in drag because these two airplanes consistently bring home all the trophies.

The original drawings and engineering studies done by Kriemendahl in 1949 were lost or destroyed, a fact that worried John Anderson, one of the several past owners of the original Shoestring. Before Anderson sold the airplane to Ray Cote, he commissioned Ketner, a Piper engineering draftsman at Vero Beach, to go through the airplane with a tape measure and dividers and come up with a set of drawings he could use for repair work in case he ever dinged it. Ketner measured until he had enough dimensions to make up a complete set of working drawings. He had an engineering study run on the main spar and it was increased in thickness to bring it up to a 10-G strength. He has proof loaded the fuselage structure to 9 Gs with no deformation.

Constructed from the conventional combination of steel tubing, wood, and fabric, the racer is powered by a 100-hp O-200 Continental engine. By 1974, the Shoestring racer had accumulated 14 first places in major air race competitions. Other recommended engines are the Continental 85-and 90-hp versions.

The aircraft first flew in 1949 and entered its first competition race in 1950.

Yellow Jacket, the first reproduction of Shoestring, was built by Jim Strode of Melbourne, Florida. The plans for the airplane are produced by Landis Ketner and Jim was building parts as fast as Landis could make the drawings. Building Shoestring Yellow Jacket took just over a year.

Strode made four different cowlings before he got the shape and weight he wanted. This one weighs only 11 pounds. The cowling, wing fairings, landing gear fairings, and the canopy fit into their own little recesses, making everything flush. The wing is completely wooden construction, with plywood skins.

Comte AC-4 Gentleman

The three-seat AC4 Gentleman, designed by Alfred Comte, was the first aircraft that has been build commercially in Switzerland. The A.C.4 Gentleman is a two-seat cabin monoplane of mixed construction.

The prototype was being flown in 1928, and the AC-4 was in production 1928-1930.

Six of the first version, powered by 90 hp Cirus III engines were produced from 1928.

A second series was produced in 1930 powered by 110 hp Cirrus Hermes or 140 hp Genet Major engines.

One machine, owned by Swissair, was re-engined with an Armstrong-Siddeley Genet Major radial.

Competition Aircraft Firebird Flyer

Single seat single engined high wing monoplane with hybrid control. Wing has unswept leading and trailing edges, and constant chord; inverted V tail. Pitch/yaw control by elevon; roll control by full span ailerons; control inputs through stick for pitch/yaw/ roll. Wing braced from below by struts; wing profile; double surface. Undercarriage has three wheels in tricycle formation; suspension on all wheels. Nosewheel steering independent from yaw control. No brakes. Aluminium tube framework, without pod. Engine mounted below wing driving pusher propeller.
In 1983 this machine was still in its prototype stage and therefore its characteristics and performances are not fully known. However, R J Davies has two original ideas in this new design. Firstly, the full span ailerons can be operated together to serve as flaps. Secondly, the motor on the Firebird Flyer (a Spitfire 250FA of 28hp or possibly later a water-cooled 220LC of 35 hp) drives a two bladed pusher propeller, which rotates about the axis of the tubular metal boom which carries the tail.
