The Pratt & Whitney R-1340 Wasp is an aircraft engine of the reciprocating type that was widely used in American aircraft from the 1920s onward. It was the Pratt & Whitney aircraft company's first engine, and the first of the famed Wasp series. It was a single-row, nine-cylinder, air-cooled, radial design, and displaced 1,344 cubic inches (22 L); bore and stroke were both 5.75 in (146 mm). A total of 34,966 engines were produced.
The Ayres Thrush, formerly the Snow S-2, Aero Commander Ag Commander, and Rockwell Thrush Commander, is an American agricultural aircraft produced by Ayres Corporation and more recently by Thrush Aircraft. It is one of the most successful and long-lived agricultural application aircraft types in the world, with almost 2,000 sold since the first example flew 68 years ago. Typical of agricultural aircraft, it is a single-seat monoplane of conventional taildragger configuration. Originally powered by a radial piston engine, most examples produced since the 1980s have been turboprop-powered.
The PAC Cresco is a turboprop-powered derivative of the Fletcher FU-24 aerial topdressing aircraft, manufactured by the Pacific Aerospace Corporation in Hamilton, New Zealand.

The Cessna 421 Golden Eagle is an American six or seven seat twin-engined light transport aircraft, developed in the 1960s by Cessna as a pressurized version of the earlier Cessna 411.
The Vultee XA-41 was originally ordered as a dive bomber. After combat experience led the Army Air Corps to believe dive-bombers were too vulnerable to enemy fighters, the contract was amended to change the role to low-level ground attack. Although the XA-41 was a potent weapons system, the design was overtaken by more advanced technology, and never entered production.
The Agusta AB.102 was an Italian helicopter produced in small numbers in the early 1960s. The aircraft was based on the mechanical components of a Bell 48 that Agusta incorporated into an all-new, streamlined fuselage. The first flight was on 3 February 1959 and the prototype was exhibited at that year's Paris Air Show in faux military colours. Only two production examples were built, operated by Elivie in a regular air service between Turin and Milan from 1961. However, the advent of turbine-powered helicopters in the 1960s soon rendered the AB.102 obsolete.
The Air Tractor AT-400 is a family of agricultural aircraft that first flew in the United States in September 1979. Type certification was awarded to Air Tractor in April 1980. Of low-wing monoplane taildragger configuration, they carry a chemical hopper between the engine firewall and the cockpit.
The Air Tractor AT-500 is a family of agricultural aircraft that first flew in the United States on 25 April 1986, manufactured by Air Tractor Inc. Of monoplane low-wing, taildragger configuration, they carry a chemical hopper between the engine firewall and the cockpit. Compared with their predecessor, the AT-500 family featured a wingspan increase of 50 in, and an additional fuselage stretch of 22 in (56 cm), allowing for a larger chemical hopper. Almost all variants offer a widened "buddy" seat or a tandem seat for a passenger, observer, or loader; trainer aircraft with full dual controls have also been offered.
The Air Tractor AT-602 is an agricultural aircraft manufactured by Air Tractor Inc, that first flew in the United States on 1 December 1995. Of monoplane low-wing, taildragger configuration, it carries a chemical hopper between the engine firewall and the cockpit. It was designed to fill a gap in the Air Tractor range, between the AT-500 series with a 500 US gal capacity and the AT-802 with a 810 US gal capacity.
The Piaggio P.166 is an Italian twin-engine pusher-type utility aircraft developed by Piaggio Aero. The aircraft model name was Portofino, and is also known as Albatross in South African military service.
The PZL-106 Kruk is a Polish agricultural aircraft designed and built by WSK PZL Warszawa-Okęcie.
The Commonwealth Aircraft CA-28 Ceres was a crop-duster aircraft manufactured in Australia by the Commonwealth Aircraft Corporation (CAC) between 1959 and 1963. The aircraft was a development of the Wirraway trainer of World War II.
The Emair MA-1 Paymaster was a 1960s American agricultural biplane aircraft built by Emair, which was part of the Hawaiian Murray company. The prototype was constructed and flown in New Zealand, with production aircraft built in the United States at Harlingen, Texas.
The Piaggio P.150 was a 1950s Italian two-seat trainer designed and built by Piaggio to meet an Italian Air Force requirement to replace the North American T-6.
The Vulcanair SF.600 Canguro was a feederliner developed in Italy in the late 1970s. Despite a number of attempts to put the aircraft into series production, only a small number were ever built.
The IAR-827 was an agricultural aircraft built in Romania in the 1970s and 1980s. The penultimate member of the family of designs that began with the IAR-821, it was, like the others, a conventional low-wing monoplane with fixed, tailwheel undercarriage, and shared the all-metal construction of the IAR-826. The prototype flew in 1976, powered by a Lycoming IO-720 engine, but the production examples that followed all had the PZL-3S.
The NAC Fieldmaster was a British agricultural aircraft of the 1980s. A turboprop powered single-engined monoplane, it was built in small numbers and used both as a cropsprayer and a firefighting aircraft.
The Spartan C4 was an American four-seat cabin monoplane designed and built by the Spartan Aircraft Company.
The Waco D Series was a series of military biplanes created between 1934 and 1937 by the Waco Aircraft Company for export to countries other than the United States. The three letter designation indicated the engine, airframe, and series. Armed versions had a -A suffix.
