The design of the EC-2 all wood low wing single seat monoplane was started by Eric Clutton in 1969. It was designed to be as simple to build as the FRED, but with aerobatic capability.
The prototype, PFA.1361 was started in Stoke-on-Trent, to be powered by a belt-reduced VW1500.
Wingspan: 23.04 ft
Designed by Eric Clutton of Stoke-on-Trent in conjuction with E.Sherry during 1957 to 1963. FRED stands for “Flying Runabout, Experimental Design,” but the design is now far from experimental, says its designer – Eric Clutton. A parasol-type single-seater, FRED has folding wings for road-towing. It has steel spring shocks for rough-field operations. Volkswagon powered.
Clutton started building the first, G-ASZY PFA.1311 cn EC/ES/1A in 1957 at Stoke-on-Trent, finished at Meir and first flown from there on 3 November 1963 with a modified Triumph 5T as FRED Series 1. It was re-engined with a Scott A.2S in 1965 to demonstrate the wide range of engines it can take. It was further re-engined in 1966 with a Lawrence radial as FRED Series II.
From 1968 it was used as a testbed for the Clutton belt-reduced VW of various sizes and drives, eventually with an EC/VW1500.
Badly damaged at Meir in 1974, it was rebuilt and flown again in mid-1975 in WW1 German markings including lozenge markings.

The Club ULM Rotor Ptenets-2 (Russian: Птенец-2, English: Chick or Fledgling) is a Russian ultralight aircraft, designed and produced by Club ULM Rotor of Kumertau, Bashkortostan.
The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a strut-braced high-wing, a two-seats-in-side-by-side configuration enclosed cockpit, fixed tricycle landing gear and a single engine in pusher configuration.
The aircraft is made from aluminum tubing, with its flying surfaces covered in Dacron sailcloth. The fuselage is made from fibreglass. Its 10.2 m (33.5 ft) span wing has an area of 12.7 m2 (137 sq ft). The tail is supported by four tubes that allow space for the pusher propeller. Standard engines available are the 50 hp (37 kW) Rotax 503 and 64 hp (48 kW) Rotax 582 two-strokes and the 60 hp (45 kW) HKS 700E four-stroke powerplant.
The aircraft was supplied as a complete ready-to-fly-aircraft for €21,000 in 2011.

A single-seat high performance sailplane designed by Roger Dickson, the Phantom featured conventional wooden construction, all-moving tailplane.
The wing section was the R.A.F.34 modified, semi-cantilever wing, with one strut on each side. No flaps or airbrakes were fitted. The undercarriage was a main skid and tail skid.
The prototype first flew on 11 June 1931, at Dunstable. The 1931 price was £300, ex-works.
The Phantom sailplane was designed and built by the company but this just about exhausted all the financial resources, and after the last advertisement had appeared in the 17 July 1931 issue of ‘Sailplane and Glider’ magazine the Cloudcraft Glider Co was declarad bankrupt.

Cloudbuster Ultralights Cloudbuster Article
The Cloudbuster made its appearance in 1981. It is fitted with a rigid wing with duralumin tube spars and ribs of high density polyurethane foam, reinforced by a layer of unidirectional glass fibre and epoxy. Wing and tail surface covering is 1.7-ounce Dacron. The leading edge is vinyl and the trailing edge is aluminium sheet bonded to the back of the spars with epoxy. At the wing tips there are semi elliptic saumons and the ailerons are hinged from a false spar.
Undecarriage was tricycle with coil-spring independent suspension and a steerable nosewheel. The main wheels are 20”, and the nose wheel is 16”. A hand-operated bicycle-type brake is fitted to the nosewheel.
The prototype Cloudbuster was equipped with a Skylark Ultra 342 motor and a 2.0 reduction gear turning a two-blade Woody’s prop measuring 58×27”, which was dropped on the initial production models in favour of the Zenoah G25B developing 20 hp at 6500 rpm. Two other options were offered for this machine; the Cuyuna 215R (20hp at 5500 rpm) with a 2.5/1 reduction drive, or the Cuyuna 430R (30 hp at 5500 rpm).
Transport by road requires a trailer, the two half wings and the horizontal tail surfaces being de mounted.
The Cloudbuster is sold as a kit at various stages of finish with or without motor at the choice of the customer. The price was dependent on the kit chosen.

The 1910 Clerget monoplane was designed and built by Pierre Clerget in France.

The Clerget-Etrich Taube Aman was a slightly modified version of the Etrich IV Taube license-built by Clerget in France for whose name appeared on the tail, Gustave Aman. Powered by an inline Clerget engine, it was completed in August but first flown in October 1910.
Émile Chesnay, a photographer and balloonist, had a monoplane built by Clement Bayard. It was equipped with a Clerget engine of 50 hp. The wings, with a span of 8.50 m resembled those of Bleriots and may have been built at their factory. The landing gear had two wheels and two curved skids. It was presented at the aviation meeting of Dijon which was held from 22 to 25 September 1910.
