Krucker Cygnet / Sea & Sky Cygnet

Krucker Cygnet at Sun ‘n Fun, 2004

The Krucker Cygnet amphibious ultralight trike was designed by J.P. Krucker and initially produced by his company Krucker Manufacturing in Sudbury, Ontario, Canada. Supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft, the aircraft was designed to comply with the Fédération Aéronautique Internationale microlight category and the US light-sport aircraft rules.

It features a strut-braced hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem open cockpit, retractable wheeled tricycle landing gear and dual floats and a single engine in pusher configuration.

The aircraft is made from bolted-together aluminum tubing, with its single surface wing covered in Dacron sailcloth. Its 10.3 m (33.8 ft) span wing is supported by struts and uses an “A” frame weight-shift control bar. The standard powerplants are the twin cylinder, liquid-cooled, two-stroke, dual-ignition 65 hp (48 kW) Rotax 582 engine, the four cylinder, air and liquid-cooled, four-stroke, dual-ignition 80 hp (60 kW) Rotax 912UL and the 100 hp (75 kW) Rotax 912ULS engines.

A number of different wings can be fitted to the basic carriage, including the North Wings Pulse 17 m2 (180 sq ft) and 19 m2 (200 sq ft) sizes. The LSA-approved wings are the North Wing Mustang 3 in 15 m2 (160 sq ft), 17 m2 (180 sq ft) and 19 m2 (200 sq ft) and the Keitek Hazard.

The Cygnet was awarded Best Trike at Sun ‘n Fun in 2005.

SLSA #99 was the Krucker Cygnet amphib trike. The SLSA completed on 3 July 2009 accoring to U.S. representative, Michael Percy, of XL Kites who imports the Cygnet to the US.

The Cygnet was later manufactured by Sea and Sky of Fort Walton Beach, Florida, United States, selling for US$49,600 (with Rotax 912) in 2011, and still in production in 2013.

K & S Jungster II

The Jungster II is a follow-up design that grew out of experience with the Jungster I. The intent was to create a plane with the same open cockpit concept but to increase speed and capacity so that it would be an acceptable cross-country airplane. The Jungster II uses the same design and construction concepts except that it is just a little bit bigger, has left the lower wing, behind in favor of a single extended parasol-type wing, and uses a welded steel-tube center section. Engines rated from 85 to 180 hp are used.

K & S Jungster I

The Jungster I was developed as an 8/10 scale version of the famous Bunker Jungsmeister aerobatic airplane. The intention was to capture many of the flying qualities of the Jungmeister in a smaller size. This all-wood, fabric-covered biplane has a swept-back wing design of about 11 degrees to keep the center of lift close to the center of gravi¬ty. It can handle engines rated from 85 to 150 hp and is a frisky single place aerobatic plane.

Kronfeld Drone / Super Drone / Planette / BAC Drone

BAC Drone G-AEJP – 10 August 1936

The 1932 Planette was a powered development of the B.A.C.VII. A single-seater, four were built.

Kronfeld Drone Article

A further development was the single-seat, single engine Drone of 1935. A lightly laden high wing monoplane of 40 ft span, the Drone was devised by Charles Herbet Lowe-Wylde by fitting a motor-cycle engine to his sailplane. The idea was to give cheap training to pilots who had already gone solo. The pusher engine was mounted on top of the wing, behind the cockpit. Two were produced and two conversion were made.

The BAC Drone was the production version of the Lowe-Wylde Planette and was first produced in 1933. B.A.C (1935) Ltd was formed in 1935 to take over production and development of the Drone.

In 1935 twenty-five of the further developed Super Drone were produced, plus 1 conversion.

The final B.A.C.VII development was the Drone de Luxe of 1935. One was built and one conversion made.

Kronfeld Drone de Luxe G-AEKV

In 1936 Kronfeld built 20 Drone monoplanes.

In 1937 the Carden Ford 10 engine of 30 hp was fitted, along with the 32 hp Bristol Cherub 3.

The Drone was also built under licence at Issy les Moulineaux in France by the Societe Francaise des Avions Nouvelles (SFAN), and at Ghent in Belgium by the Societe Gantoise des Avions sans Moteur.
