The Warner Scarab Junior was an American, five-cylinder, air-cooled, radial aero engine first run in November 1930. It was a scaled-down derivative of the seven-cylinder Warner Scarab, developing 90 hp (70 kW) against the Scarab’s 110 hp (80 kW).

First run in November 1927, the Warner Scarab is an American seven-cylinder radial aircraft engine, that was manufactured by the Warner Aircraft Corporation of Detroit, Michigan in 1928 through to the early 1940s. In military service the engine was designated R-420.

Amongst the many uses for the Scarab, the engine was fitted to the Cessna Airmaster and the Fairchild 24 (UC61 or Argus). Notably, in 1942, it was put into use powering the Sikorsky R-4, the first helicopter to be put into production.
Warner Scarab
The Warner 145 and 165 HP engines are the most commonly seen of the small radials for US-built pre-WWII era aircraft, in large part because of good parts availability due to the engines having been used on WWII Fairchild UC61s and Meyers OTWs.
Warner engines are also in demand as realistically sized, though far more powerful, replacement powerplants for many replica or restored World War I era airplanes which were originally fitted with rotary engines.
An air or hand-electric starter were available at extra cost.

The TLAR was a locally designed and built ultralight, conforming to NZ CAR Part 103. Of conventional controls, the TLAR first flew on 22 May 1997. First registered, ZK-TLR, to RJ Ward, Christchurch, New Zealand, on 4 June 1997.
In 2009 the registration was cancelled as the TLAR had been dismantled.
The Ward RA Super BD-4 N62RW c/n 99 was a hybrid of a Bede BD-4 fuselage, a Cessna 172’s undercarriage, and a Swearingen SX-200’s nose and engine. The cruise was about 220 mph.
The Ward P.45 Gnome was designed and built by M. Ward at Scarle, Lincs, as the smallest aircraft in Britain.
All-wood construction, it was powered by a Douglas motor cycle engine conversion. First flown on 4 August 1967 at Wigsley, piloted by R.A.Fixter. Sold to R.A.Fixter in 1968, it was registered G-AXEI about 1968.
It later went on display at the Lincs Aviation Museum, Tattershall.

The Warchalowski V was built by Autoplan, Austria.
1911 Warchalowski V single-seater pusher biplane
From 1910 to 1912 Adolf Warchałowski started designing and building aircraft based roughly on Farman design. Within two years he built 15 aircraft that differed with various details. Warchłowski’s planes were highly succesful for a time and gained several records of Austria.
The Warchalowski V (“Vindobona Racer”), was flown by the constructor on June 7, 1911. It was a development of the Warchalowski IV and was reported to have a single rudder and a Gnôme engine. Examples were built. Two Warchalowski V aircraft took top positions in the Air Meeting in Wiener-Neustadt (11-18.06.1911). On 9.08.1911, a night flight over Vienna was made on a plane equipped with headlights. The VI version was reported to have a single horizontal tail was used and a Daimler inline engine. In August and September 1911, three examples were built. On this plane, in August and September 1911, the constructor participated in military exercises. One was broken down by J. Sablatnig on October 1, 1911, a second was crashed by Sablatnig on August 19, 1911 during a flight around lower Austria, where he reached a speed of 106 km/h.

The scale Zero is built around a plywood box core and covered with styrofoam and fiberglass. Plans have been produced for this and two other ½-scale World War II replicas by War Aircraft Replicas. All use the same common wooden fuselage box and wing spar construction in order to duplicate the various fighter aircraft. Polyurethane foam is shaped and covered with high-strength fiberglass cloth and laminating epoxy resin to form a rigid, yet light structure. Landing gears are of air/oil oleo type, with either electrical or manual retract and have a built-in emergency release. Engines vary from 65 hp to 125 hp, which accounts for variations in perform¬ance. Authentic three and four bladed props are available. Features fully retractable landing gear, sliding canopy, and detachable wings.
