Four versions of this aircraft (LSA) were produced: the standard series and the wide body model, the stretch model and four stroke model. The kit for the Excalibur II features prebuilt tail surfaces, wings, ailerons end fuselage, and all the controls are already installed. Build time for the kit is estimated at 100 to 200 hours. Options include: 60-hp HKS 700E air-cooled 4-stroke or 4O-hp Rotax 447 air- cooled 2-stroke engine, instruments (ASI, altimeter, tach, dual CHT dual EGT, panel-mounted compass, ignition switch), standard or amphibious floats, fiberglass wheel pants, BRS ballstic emergency parachute, doors, strobe lights and paint materials. Construction is 6061-T6 and 2024-T3 aluminum tube airframe with chromoly steel weldments where needed, stainless steel pop rivets and AN or military spec hardware. Wings and surfaces are covered with Superflite fabric. No welding or machining is necessary and all the critical work is completed at the factory.

The Everson brothers went on to build several aircraft, including one with a single-seat twin-engined design called Evo III. This aircraft, in which the pilot’s head was inches away from the propeller tips, was initially condemned by the authorities. Nevertheless it remains the only twin-engined homebuilt aircraft made in New Zealand.
The Everson gyrocopter was built by Ron and Ernie Everson in the early 1960s. The gyrocopter was tested at Muriwai Beach, New Zealand, where it was tethered to a vehicle and driven at high speed. The aircraft did not receive a Certificate of Airworthiness. Ron Everson donated the gyrocopter to MOTAT in 1982.
Using a Stinson SR5A Reliant as a donor, Evergreen Aviation Services began on the wings. The flap hardware was removed and each wing was shortened by 24 in by cutting off the tips, and the lift strut and jury strut mounts were moved inboard by 19in. The inboard ribs were redesigned for the removal of the flaps and to make provision for a new 10ft 6in aileron. They also had a change in profile to blend in with the centre section.
The 7ft wide centre section was built from scratch, considering only two photographs were available for reference. This section has an hour-glass shape and the middle of the trailing edge goes so far forward that it is actually 12in forward of the rear spar. It is made of 4130 steel tubes tubes with some flat steel used for reinforcements.
Based on a photograph of the bare fuselage structure and the undercarriage common with the Reliant, a drawing of the fuselage was computer generated, and then built.
Struts were created based on 20 odd photographs, and aileron cables, fuel lines, pitot and static lines, electrical and fuel vent lines all go through the struts.
The swivel only tailwheel was modified to lockable. The cowling is from a UC-78 Bobcat, turned 90 degrees, hinging the top so it would ‘clam-shell’. They added blisters for cylinder clearance.
Evergreen designed and built the throttle quadrant, and copied the elevator trim controls from photographs. All of the engine plumbing are copper lines with brass fittings.
A single seat partially enclosed autogyro, first flown 1984 and sold in assembled form. Built of bolted-together square aluminium tube. Stream lined body enclosure, wheel pants, molded fuel tank mounted low behind seat.
One of the earliest British tractor monoplanes, designed in 1908 by E. I. Everett and constructed by Everett Edgcumbe and Co. Ltd., of Colindale. The machine was powered by a four-cylinder 35 h.p. J. A.P. engine which drove a 6 ft. diameter propeller. The framework was of wood with fabric covering overall; the flying surfaces were double-covered. Warping was used for lateral control, and this was operated by turning the hand-wheel on the control column, the fore-and-aft movement of which actuated the elevators. The engine was water-cooled, its radiator being carried at an angle under the nose of the fuselage.
Tests were carried out in a field at Colindale which was to become part of the London Aerodrome at Hendon. The plane was nicknamed “The Grasshopper”, as it failed to fly properly and succeeded only in making hops from the ground during trials made on 6th and 7th December, 1910, by Bernard Clutterbuck and again during January, 1911, by E. I. Everett. [The machine has been incorrectly identified as the Prosper monoplane (Canada, 1909)]
A tractor monoplane, designed and built by W. Heinrich Evers of Lamstedt, Germany, and powered by a three-cylinder Hilz engine. It was tested in December 1910 at the Winzer Heide near Lamstedt. It crashed, but was later repaired.
