The RT-4 Seagull motorglider was created by Vlado Kensgailos with Silutes ASK.
The M-72 motorcycle engine of 22 hp power spun a 1.7 m diameter propeller. The propeller speed of 2500 rpm, with engine speeds 4800 rpm. Fuel tank – 20 liters, filled the first third of the wingspan, gravity feed into the carburetor.
On the right side, the cockpit door is made with a plexiglass panel. Instruments were compass, vertical speed indicator, altimeter, speed indicator, slip indicator, tachometer and the magneto switch.
The main undercarriage wheels came from a “Vyatka” scooter and the tail wheel of solid rubber.
The motorglider was built in the winter, spring, and summer of 1961 before the first flight.

Charlie Kenny of Clydevale near Balclutha, New Zealand, a Jodel enthusiast built a Jodel D 9 ZK-AKR but believed he could build a better Jodel so he designed and built his D 150X Governor ZK-CCD (c/n AACA 360/2).
He incorporated what he reckoned were the best bits of all the many Jodel models. Charlie’s D 150X has the rudder from the D 150, the all-flying tailplane from the D 18 (but bigger), the luggage locker from a D 140 and the wing airfoil is that of a D 18 but again applied to a bigger wing. The wing has split flaps that drop down from the trailing edge.
Charlie has also made the fuselage wider than the D 150 at 44 inches while he has moved the seat back 3 inches and sloped the seat to 30 degrees which gives a very roomy cockpit. The windscreen is from a Fletcher FU 24 and it has gull wing doors.
The Jodel is powered by a 1.9 litre Peugeot turbo diesel engine (from a Peugeot 405) that produces around 100 HP. It has a belt reduction drive designed by Wayne Affleck of Invercargill that gives 2400 rpm at the propellor for 3300 rpm engine revs. The engine is water cooled and the radiator in located in the starboard wing root with the battery located in the port wing root. Charlie developed the engine himself but later found out that Jean Delemontez (the del in Jodel) and Jacques Vion had developed their Delvion diesel engine along very similar lines. The diesel engine is very economical using only around 10 litres per hour at cruise.
The dimensions of Charlie’s D 150X Governor are similar to the D 150 Mascaret which has a length of 6.30 metres (20 feet 8 inches), a wingspan of 8.15 metres (26 feet 9 inches) and a wing area of 141 square feet.
It was first registered on 7 November 2011. The first flight was on 2 July 2015. Charlie says his aircraft flies really well and he had flown about 65 hours in, although it hasn’t flown in the last year or so.
Charlie Kenny has designed and built his D 150X entirely by himself in his shed, as well as sorting the entirely clean sheet engine conversion and all its systems.
The Kennedy Giant was a British biplane heavy bomber designed by Kennedy Aeroplanes Ltd. during the First World War. The design was an imitation of works by Igor Sikorsky, with whom the owner of Kennedy Aeroplanes Ltd., Chessborough J. H. Mackenzie-Kennedy, had ostensibly worked prior to setting up the company.
The four-bay, unstaggered wings spanned 142 feet; ailerons were fitted to the upper wings only, their control rods extending along the top of the leading edge, and the wing overhang being braced by pairs of outraked struts. The four engines, mounted in tandem pairs in nacelles on the lower wings, were very early British-built examples of the Canton-Unne/Salmson Z9 nine-cylinder water-cooled radials, each of which was provided with a pair of large vertical radiators on the sides of the nacelles.
The fuselage was of rectangular section over its entire length and tapered towards the tail only in plan. It provided fully-enclosed accommodation for the crew, the pilot being situated in the extreme nose, with individual compartmented cabins aft. The tail surfaces were of inadequate area, the tiny rudder (later enlarged) being unbalanced and without a fixed fin. The undercarriage was a complicated structure of multiple V-struts and skids.
The aeroplane was a notorious failure; its size meant that construction had to take place in an open field at the Fairey factory at Heston as none of the hangars near Hayes, Middlesex, where the prototype was assembled, were large enough to house it.
Supply of the Sunbeam engines, manufactured under licence by the Dudbridge Iron Works Ltd of Stroud, were afforded very low priority (and were not subject of official trials until May 1919). Early examples were rated at only 200hp and, with these, the Giant was made ready for flight at Hendon late in 1917.
Movement needed two trucks and seventy men, but these efforts broke the tail of the aircraft. It was repaired, but the fuselage shortened by 10 feet (3,048 m).
This power proved insufficient to gain true flight, and despite being taxied at full throttle downhill, the pilot, Lieut Frank T Courtney, only managed to lift the mainwheels off the ground for a short hop with the tailskid still dragging along the ground. The prototype was left derelict at Northolt Aerodrome for a number of years.

First flown in 1980, the KB-2 Gyroplane has quite a few features that distinguish it from other similar aircraft. These include: an aircraft-type joystick for con¬trol; its fuel tank seat which is molded from polyurethane to save on weight and add to the clean-looking design; its choice of rotor blades and its wheels. Construction has been simplified by packaging into seven separate kits (airframe, landing gear, rotor head, rotor blades, rotor hub, joystick, rudder/horizontal stabilizer and an optional kit for a prefab metal tail). Engine: 72 or 90 hp McCulloch, VW, or similar.

The second, and last, plane constructed by the Cabool R-4 school students was a Cabin Biplane named the KG Special. The plane was designed by Dr. Harry B. Kelly, DDS and Bill Ghan. During the class, students drew the plans and constructed the plane. This project continued on into a second school year as both drawing and building the plane took more time. The completed plane was taken to the West Plains airport, assembled and flown. Bill Ghan was the first to fly this plane
The E-60 is one of many attempts to create a cheap and efficient training aircraft that combines high flight performance, small size and modern appearance. After conducting a series of studies, French designer Louis Bechereau began construction of such a machine in 1939. Its design was distinguished by a very small size – length 4.9 m, wingspan – 5.4 m with an area of only 3 sq.m. To ensure flights at ultra-low speeds, an absolutely new aileron system was installed on the E-60. All the originality of the plane was due to this ” wing in drawer ” design. The first works on the drawer wing had started in 1936, and found their first application on the Kellner-Béchereau E.1. This system consisted of a wing in two parts, the movable rear part of which could move backwards by lowering for landing, like the Fowler flaps. The mobile part of this wing could also partially retract, the two extreme positions corresponding to the “low speed” configuration (fully free wing) and “high speed” configuration (mobile wing partially retracted).
Tests carried out on September 22, 1939 at the Eiffel Laboratory allowed to establish the polar (curve characterizing the profile). This resulted in a profile with low drag (therefore allowing high speeds) and high lift, allowing a large speed difference. However, the high angles of attack were hardly usable, due to the lack of visibility when the aircraft was taking a very nose-up attitude.
The airplane was a monoplane with a mid-wing and a streamlined fixed landing gear. The construction was carried out in spruce and plywood. The fuselage had only three frames: the sheet metal firewall, the pilot’s backrest and the sternpost support. The engine was a Walter Micron of 62 hp, driving a two- bladed propeller. The engine rested on a frame of steel tubes. The simplified landing gear consisted of a single axle.
The completion of the construction of the E-60 just coincided with the competition announced by the fleet on a training aircraft. The plane left the factory in the early days of March 1940 and was brought by road to Buc (Yvelines) and reassembled for his first flight. This took place on 7 March 1940. The test pilot was François Bruneteau. He took off from the 900m grass runway, which was in poor condition that day, plowed by the landings of British heavy aircraft the day before. Takeoff was bumpy. As soon as it took off, the plane took a strong 45- degree right tilt, due to the improper adjustment of the slots. The pilot’s skill allowed him to reduce the incline to 30 degrees and bring the plane back onto the runway, the left wheel touching first. The following tests focused on longitudinal and transverse stability, and revealed acute problems.
A presentation flight was carried out on April 25, 1940 by François Bruneteau before the Naval Air Commission, which was very interested. This flight, which lasted 40 minutes, highlighted the qualities of the aircraft. Due to its small size, it became practically invisible at 1,500 meters. The Navy planned to use it as a reconnaissance aircraft. The aircraft was able to be fitted with light bombs.
The last two flights took place on June 1 and June 3, 1940. The first included engine temperature tests, and the second included level speed tests at different altitudes, recorded with the barograph. This last flight, lasting 1 hour 45 minutes, almost ended badly for François Bruneteau. A leak of ethylene fuel took place, the vapors spreading in the cockpit.
Before the advance of the Germans, who were already at the gates of Paris, the prototype was evacuated to the South on June 5, 1940. Mounted on a truck, it left Paris by the Porte de Saint-Cloud, when the Germans had arrived at Le Bourget. The destination was the fall-back factory in Alençon, but the Germans were already there. The truck took the direction of Castelnaudary. François Bruneteau left the convoy at Clermont-Ferrand to reach Marseille where he embarked on a boat bound for North Africa. From there, he joined the Free French Air Force in London. The truck continued to Air Base 745 Aulnat, where the plane was hidden throughout the war.
After the war a scrap dealer, “aviation fan”, found the prototype among the wreckage of planes which he found in Aulnat and sold it to his test pilot, François Bruneteau, or rather to his wife, who offers it to her husband as a Christmas present. François Bruneteau completely restores the aircraft (except the original paint and without engine) on his property in Èze-sur-mer (Alpes-Maritimes). In 1975, following the publication of the article in the Fanatique de l’Aviation (number 72), the Air and Space Museum contacted the Bruneteaux. The aircraft was donated to the museum.
