The Wren 460 is a STOL conversion of a Cessna 180 or 182 airframe.
The Wren 460 traces its history to the Skyshark, a modification of the earlier Robertson Skylark SRX-1, built by James Robertson, son of Robertson Aircraft Corporation founder William B. Robertson, in the late 1950s. The Skyshark incorporated a number of modifications, most notably a canard fitted with elevators in the slipstream behind the propeller. It was a technological success but too expensive to produce.
Robertson incorporated many features of the Skyshark into the Wren Aircraft Company's Wren 460. A conversion of the Cessna 180 or 182 airframe, the Wren 460 featured full-span double-slotted flaps, movable spoilers to assist the ailerons with roll control, and an optional reversible pitch propeller for shorter landing runs. Like the Skyshark, the Wren 460 also featured a set of canards immediately behind the propeller, taking advantage of the propeller's airstream and allowing the nose to pitch up even when the aircraft is motionless. [1] [2] The stall angle of the airfoil was also changed from 16 to 20 degrees by the addition of a drooped leading edge cuff, a modification that would later be incorporated in the standard 182. [3]
The Wren 460, modified from a Cessna 182A, made its first flight in January 1963, and received FAA certification on June 30, 1964. [3]
Pilots praised the Wren 460 for its STOL performance. Kevin Brown of Popular Mechanics noted that it "lands like a carrier plane", but also noted that such a touchdown was "quite hard". [1] Despite the publicity of its initial release, few were built due in part to its price, which was over twice that of a stock Cessna 182 at the time. Wren Aircraft eventually went bankrupt in 1969 after the United States military rejected its projects. [3]
The type certificate of the Wren 460 was sold to Galen Means, and was again sold to Todd Peterson in 1977. Peterson, the owner of Advanced Lift Systems (later Peterson's Performance Plus), began production of the Wren 460 once again as the Wren 460P, this time modified from used 182 airframes of newer models as opposed to the new, early model airframes of the original. Unlike the original, the Wren 460P did not have the option of a reversible propeller as Peterson believed it offered too little benefit for its cost. By 1986, a Wren 460P cost less than a new 182 by almost $20,000. [3]

General characteristics
Performance
The Cessna 172 Skyhawk is an American four-seat, single-engine, high wing, fixed-wing aircraft made by the Cessna Aircraft Company. First flown in 1955, more 172s have been built than any other aircraft. It was developed from the 1948 Cessna 170 but with tricycle landing gear rather than conventional landing gear. The Skyhawk name was originally used for a trim package, but was later applied to all standard-production 172 aircraft, while some upgraded versions were marketed as the Cutlass, Powermatic, and Hawk XP. The aircraft was also produced under license in France by Reims Aviation, which marketed upgraded versions as the Reims Rocket.
The Cessna 152 is an American two-seat, fixed-tricycle-gear, general aviation airplane, used primarily for flight training and personal use. It was based on the earlier Cessna 150 incorporating a number of minor design changes and a slightly more powerful engine with a longer time between overhaul.
The Cessna 182 Skylane is an American four-seat, single-engined light airplane built by Cessna of Wichita, Kansas. It has the option of adding two child seats in the baggage area.
The Cessna Skymaster is an American twin-engine civil utility aircraft built in a push-pull configuration. Its engines are mounted in the nose and rear of its pod-style fuselage. Twin booms extend aft of the wings to the vertical stabilizers, with the rear engine between them. The horizontal stabilizer is aft of the pusher propeller, mounted between and connecting the two booms. The combined tractor and pusher engines produce centerline thrust and a unique sound. The Cessna O-2 Skymaster is a military version of the Cessna Model 337 Super Skymaster.
The Cessna AT-17 Bobcat or Cessna Crane is a twin-engine advanced trainer aircraft designed and made in the United States, and used during World War II to bridge the gap between single-engine trainers and larger multi-engine combat aircraft. The commercial version was the Model T-50, from which the military versions were developed.
The Piper PA-18 Super Cub is a two-seat, single-engine monoplane. Introduced in 1949 by Piper Aircraft, it was developed from the PA-11 Cub Special, and traces its lineage back through the J-3 Cub to the Taylor E-2 Cub of the 1930s. In close to 40 years of production, over 10,000 were built. Super Cubs are commonly found in roles such as bush flying, banner towing and glider towing.
The Cessna 210 Centurion is a six-seat, high-performance, retractable-gear, single-engined, high-wing general-aviation light aircraft. First flown in January 1957, it was produced by Cessna until 1986.
The Cessna 188 is a family of light agricultural aircraft produced between 1966 and 1983 by the Cessna Aircraft Company.
The Cessna 310 is an American four-to-six-seat, low-wing, twin-engine monoplane produced by Cessna between 1954 and 1980. It was the second twin-engine aircraft that Cessna put into production; the first was the Cessna T-50.
The Cessna 414 is an American light, pressurized, twin-engine transport aircraft built by Cessna. It first flew in 1968 and an improved variant was introduced from 1978 as the 414A Chancellor.
The Velocity XL is an American amateur-built aircraft, produced by Velocity, Inc. It is an enlarged version of their Velocity SE canard pusher design.
The Soloy Pathfinder 21 was a twin-engined, single-propeller, turboprop aircraft. It is a modification by Soloy Aviation Solutions of a Cessna 208 Caravan airframe. First flown in 1995, the aircraft was essentially a stock Cessna 208 airframe that has been stretched by 72 inches (1.83 m) with structural reinforcement, powered by twin Pratt & Whitney Canada PT6D-114A engines in a side-by-side Dual Pac configuration in place of the original single engine.
The Beagle A.61 Terrier is a British single-engined monoplane built by Beagle Aircraft.
The Bellanca Viking and Super Viking are a series of single-engine, four-seat, high performance, retractable gear aircraft manufactured in the USA during the 1960s and 1970s. The aircraft developed through modifications of classic designs by the aviation pioneer Giuseppe Bellanca. A total of 1,356 Vikings have been produced with most production between 1968 and 1975.
The PZL-105 Flaming (flamingo) is a Polish short-takeoff-and-landing (STOL) utility aircraft designed by PZL "Warszawa-Okęcie". It remained a prototype.
The Robin HR100 is a French four-seat light monoplane, designed by Chris Heintz and built by Avions Pierre Robin as metal-winged version of the Robin DR253 Regent.
The SIAI-Marchetti SM.1019 is an Italian STOL liaison monoplane built by SIAI-Marchetti for the Italian Army. It is a turboprop-powered derivative of the Cessna O-1 Bird Dog.
The O'Neill Model J Magnum, also called the Magnum Jake and the Magnum Pickup, is a homebuilt aircraft design for bush flying operations similar to the de Havilland Beaver.
A three-surface aircraft or sometimes three-lifting-surface aircraft has a foreplane, a central wing and a tailplane. The central wing surface always provides lift and is usually the largest, while the functions of the fore and aft planes may vary between types and may include lift, control and/or stability.
The Javelin V6 STOL is an American STOL homebuilt aircraft that was designed and produced by Javelin Aircraft of Wichita, Kansas. When it was available the aircraft was supplied in the form of plans for amateur construction.
