The Brumby Aircraft Brumby 610 Evolution is an Australian single-engined, two-seat, training or touring cabin monoplane. The aircraft is built by Brumby Aircraft Australia as a production or kit aircraft at Cowra Airport near Cowra, New South Wales, Australia. Designed to meet regulations governing light sport aircraft (LSA), it was developed from the Brumby 600.

Design and development
The Brumby 610 is a high wing development of the low-wing Brumby 600. It is a monoplane of all-metal construction. It has a fixed tricycle landing gear and an enclosed cockpit for two in side-by-side configuration. It can be powered by a Lycoming IO-233, Rotax 912ULS or Jabiru 3300 engine, driving a wooden two-blade propeller.

Specifications
Piper continued operations in Lock Haven throughout World War II, building military versions of its J-3 Cub as the L-4 Grasshopper. A total of 5,941 powered aircraft were built by the company for the US armed forces during the war, as well as training gliders, and aircraft components for other manufacturers, but its main contibution to the war effort was in the fabrication of steel masts for mounting radar antennas. In 1946 the company opened a new factory in Ponca City, Oklahoma and transferred production of the Cub from Lock Haven. That year Piper led the American industry in light aircraft production. Almost 7,800 of the 35,000 civil aircraft built in the United States that year were Pipers, but a strike led to a shortage of steel tubing, interrupting production, and 1,900 workers had to be suspended as a result.
 * 1940s

The following year the postwar general aviation boom ended. Piper's output reached 3,500 aircraft, less than half its 1946 total, and the company suffered an operating loss of more than $560,000. In June that year the board of directors, under pressure from the company's creditors, replaced William Piper in his role as general manager with William Shriver, a former Chrysler executive. Piper's workforce was cut and cut again, from 2,607 employees in February 1947 to less than a thousand when Shriver joined the company in June, to just 157 by the end of the year after he closed the Ponca City factory. product line was expanded with the introduction of the PA-14 Family Cruiser and PA-15 Vagabond. In 1948, with two thirds of its workforce laid off, Piper only lost $75,000, but it found itself no longer the leader in a shrinking market, falling behind Cessna, which itself only delivered 1,600 aircraft; the Ponca City factory was closed. At the end of 1948 Piper bought the Stinson Aircraft Company for $3 million and Shriver left the company, being replaced by August Esenwein.

Design and development
The PA-23 was the first twin-engine Piper aircraft and was developed from a proposed "Twin Stinson" design, inherited when Piper bought the Stinson Division of the Consolidated Vultee Aircraft Corporation. The prototype PA-23 was a four-seater low-wing all-metal monoplane with a twin tail, powered by two 125 hp Lycoming O-290-D piston engines; it first flew on 2 March 1952. The aircraft performed badly and it was redesigned with a single vertical stabilizer (removed from one of the two PA-6 Sky Sedans that Piper had built in the mid-1940s) and an all-metal rear fuselage and more powerful 150 hp Lycoming O-320-A engines. Two new prototypes of the re-designed aircraft, now named Apache, were built in 1953 and entered production in 1954; 1,231 were built. In 1958 the Apache 160 was produced by upgrading the engines to 160 hp (119 kW); 816 were built before being superseded in 1962 by the Apache 235, which was a derivative of the Aztec, fitted with 235 hp (175 kW) versions of the engines used on the Aztec and swept tail surfaces (119 built). In 1958 an upgraded version with 250 hp (186 kW) Lycoming O-540 engines and a swept vertical tail was produced as the PA-23-250 and was named Aztec. These first models came in a five-seat configuration which became available in 1959. In 1961 a longer nosed variant, the Aztec B, entered production. The later models of the Aztec were equipped with IO-540 fuel-injected engines and six-seat capacity, and continued in production until 1982. There were also turbocharged versions of the later models, which were able to fly at higher altitudes.

The United States Navy acquired 20 Aztecs, designating them UO-1, which changed to U-11A when unified designations were adopted in 1962.

In 1974, Piper produced a single experimental PA-41P Pressurized Aztec concept. This concept was short-lived, however, as the aspects of the Aztec that made it so popular for its spacious interior and ability to haul large loads did not lend themselves well to supporting the sealed pressure vessel required for a pressurized aircraft. The project was scrapped, and the one pressurized Aztec produced, N9941P, was donated to Mississippi State University, where it was used for testing purposes. In 2000, N9941P was donated to the Piper Aviation Museum in Lock Haven, Pennsylvania, on the condition that it never be flown again. It now sits there on display.

In this edit posted on the ProjectAviation talk page on 11 July, TTT poses a question regarding merging of several Sikorsky S-70/H-60 family articles. In the next four hours two Users reply to disagree with the proposal, one based on there being sufficient differences between the articles' subjects to warrant separate articles; the other based on Article size. About 9.5 hours after posing the question, TTT posts material for new article about S-70/H-60 helicopter family in his/her (from now on I will refer to TTT as being male) Sandbox; the material includes the Sikorsky S-92 and Sikorsky S-76, which - not least because Sikorsky has given them different Model numbers - are obviously not S-70s and are not members of the S-70/H-60 family. Shortly after, he posts again on the WP:AV talk page, announcing the material in his Sandbox as a "rough draft".

A bit more than 12 hours later, TTT saves the new article "List of Sikorsky S-70 Models" to mainspace; the article is a copy-and-paste of the material in his Sandbox and includes the S-76 and S-92. About 21 hours later, this User comes across the article after looking at a list of new articles; after seeing that it includes the S-76 and S-92, I remove the material related to those two types from the article. About 90 minutes later TTT reverts my edit. Six hours after that, I check the article and find that my reverted has been undone and I remove it again, then leave a short message on TTT's talk page telling him that the S-76 is diferent to the S-70 and giving a couple of examples of the differences. Shortly afterwards, TTT replies on my talk page, ignoring one example of the differences and "explaining" the other - apparently I have not changed his mind at this stage.

An hour after reverting my edit, and having had no further responses to his first proposal in the intervening 38 hours or so - and adding to/altering his original proposal here and here in the meantime - TTT starts new topic, proposing the same thing, but for nine articles, including the S-92 and its military version the Sikorsky CH-148 Cyclone - neither of which is a member of the S-70/H-60 family, although they do share some of the same components in their respective drivetrains (although there are nine variants/types mentioned in the topic header, this User could only find eight articles; it should be noted however that TTT later edited the topic header to refer to seven articles). A quarter of an hour later another User makes a response here, advising that TTT should seek consensus. Forty minutes after that, another user disagrees with the proposal, pointing out at the same time that the S-92 is a different helicopter. Over the next hour, discussion by TTT and three other Users ensued, in which it emerged that there was no agreement among those Users to TTT's idea of merging the articles and during which (in this edit) TTT implies that he has the S-76 in mind as being a merger candidate.

The Super V is a twin-engine conversion of the Beechcraft Model 35 Bonanza, so named because the Model 35 is also known as the "V-tail Bonanza". Initially developed in the mid-1950s, the conversions were performed by a number of different companies in the United States and Canada during the early 1960s, the majority by Bay Aviation. Although Beechcraft had produced an aircraft it called the Twin Bonanza since 1952, this was a considerably-larger design; thus the Super V can be considered a true "Twin Bonanza". Beechcraft developed its own twin-engine version of the Bonanza in the mid-1950s &mdash; the Model 95 Travel Air; this married the fuselage of the Bonanza to the tail of Beechcraft's Mentor military trainer aircraft and the same engines as used by the Super V.

Design
The initial basis of the conversion was small-tailed Model 35, A35 and B35 aircraft.

Development
Development of the Super V began in 1955 in Tulsa, Oklahoma, when a pilot named David G. Peterson devised the concept of fitting two engines to the single-engined Bonanza. His company Peterson Skyline performed the first conversion. By 1958 the rights to the design had been acquired by Oakland Airmotive, a company based at Oakland International Airport engaged in converting World War II-era Lockheed PV-2 Harpoons into business aircraft. Oakland Airmotive continued to develop and test the Super V, until the Federal Aviation Administration (FAA) awarded a type certificate in January 1960. The FAA decided that the modifications were so substantial, the Super V should be treated as a new type.

The internal airframe was strengthened considerably in the conversion. In fact two Type Certificates were issued, one for aircraft converted in the United States, and another for aircraft converted in Canada.
