The '''Zenith STOL CH 701''' and '''CH 750''' are a family of light, two-place kit-built [[Engineering:STOL|STOL]] aircraft designed by Canadian aeronautical engineer [[Biography:Chris Heintz (aeronautical engineer)|Chris Heintz]] through his Midland, Ontario, based company, Zenair. The CH 701 first flew in 1986 and the design is still in production.<ref name="KitplanesDec2011">Vandermeullen 2011, p. 77.</ref><ref name="KitPlanes">Kitplanes Staff  2007, p. 80.</ref> The CH 750 was first introduced in 2008.<ref name="Z750">[http://www.zenithair.com/stolch750/index.html "STOL CH 750 Light sport Utility."] ''Zenith Aircraft Company'', July 2008. Retrieved: September 4, 2017</ref> The CH 701 was later developed into the four-place [[Engineering:Zenith STOL CH 801|Zenith STOL CH 801]].<ref name="KitPlanes"/><ref name="WDLA11">Bayerl et al. 2011, p. 128.</ref>

The kit is produced and distributed in the US by the Zenith Aircraft Company of Mexico, Missouri, and complete drawings, including blueprints and manuals, are also available for the design. In Europe, the CH 701 was manufactured under license by Czech Aircraft Works (CZAW) from 1992 until 2006, when the license agreement was ended.{{TOC limit|limit=2}}

==Design and development==
Designed for off-runway operations, the all-metal CH 701 has many features that contribute to the aircraft's capabilities, such as a high-lift wing with full-span, non-movable [[Engineering:Leading edge slot|leading edge slot]]s, an all-flying [[Engineering:Rudder|rudder]], large tires, flaperons and an inverted elevator. Heintz also designed a unique tricycle gear amphibious float system for the CH 701.<ref name="WDLA11" />

Standard engines used are the {{convert|64|hp|kW|0|abbr=on}} Rotax 582 two-stroke, the {{convert|80|hp|kW|0|abbr=on}} Rotax 912UL, the {{convert|100|hp|kW|0|abbr=on}} Rotax 912ULS and the {{convert|85|hp|kW|0|abbr=on}} Jabiru 2200 four-stroke powerplants.<ref name="WDLA11" /><ref name="ZenithEngines">[http://www.zenithair.com/stolch701/7-engine.html "STOL CH 701 Engine."] ''Zenith Aircraft'', January 12, 2009.

The STOL CH 701 has the unique distinction of being what is probably the most copied light aircraft in production today. Several dozen unauthorized versions have been produced around the world.<ref name="WDLA11" /><ref>[http://www.zenithair.com/stolch701/7-photo-copies.html 'STOL CH701.'] ''Zenith Aircraft''.

Designed to the Light Aircraft Manufacturers Association of Canada (LAMAC) design standard DS 10141, in its native country of {{wipe|Canada}} the CH 701 can be built and flown as a basic ultralight, advanced ultralight or amateur-built.<ref>[http://www.tc.gc.ca/civilaviation/general/recavi/Ultralight/ULTransitionStrategy/menu.htm "Ultra-light Transition Strategy."] ''Transport Canada'', April 2007.

American pilots may fly the CH 701 under Light-sport Aircraft rules or as an experimental amateur-built.<ref name="KitPlanes"/> The CH 750 is designed to comply with the US Light sport aircraft rules.<ref name="Z750"/>

==Operational history==
By the fall of 2007, 750 CH 701s had been completed and were flying.<ref name="KitPlanes"/> In July 2014, representatives of the company gathered volunteers of the EAA Airventure airshow to build a CH-750 kit in a one-week timeframe.<ref>[https://issuu.com/eaahq/docs/avt_072714_final2 "Aviation community unites behind one week wonder."] ''Airventure Today'', July 27, 2014, p. 4.

==Variants==
;STOL CH 701 
:Original version. 960lbs gross and 10 gal header tank. steel spring gear and Rotax 503.<ref>{{Cite web |title=Zenith STOL Serial No. 001 flies again — General Aviation News |url=https://generalaviationnews.com/2020/07/07/zenith-stol-serial-no-001-flies-again/ |access-date=2023-05-07 |website=generalaviationnews.com |language=en-US}}</ref>
;STOL CH 701SP
:Comes with two standard {{convert|10|u.s.gal}} wing tanks, solid aluminum spring gear. Smaller refinements to achieve a gross weight of 1100 lbs (500 kg).<ref>{{Cite web|url=http://www.zenithair.com/stolch701/7-perf.html|title=STOL CH 701 Performance and Specifications: Real Short Take Off and Landing performance|website=www.zenithair.com|access-date=21 September 2018}}</ref>
;STOL CH 750
:Introduced at AirVenture 2008, the STOL CH 750 has an enlarged cabin with wider doors and is optimized for US Light Sport Aircraft rules with a maximum takeoff weight of 1320 lbs (600 kg). Builders may also opt to register it for operation on water at 1430 lbs (650 kg) while remaining within the LSA limits, or as an experimental amateur-built aircraft up to 1440 lbs (655 kg.)<ref name="Z750"/><ref name="WDLA11" /> The STOL CH 750 was also to be factory-built by AMD as a Special Light Sport Aircraft but as of 2014 is listed by the FAA as no longer produced as an SLSA.<ref>Federal Aviation Administration, [http://www.faa.gov/aircraft/gen_av/light_sport/media/SLSA_Directory.xls "List of Approved SLSA."] ''FAA''.

[[File:CH750cruzer.jpg|thumb|right|CH750 Cruzer]]
;CH 750 Cruzer
:Introduced at Sun 'n Fun 2013, the CH-750 Cruzer uses a new wing without the leading-edge slats of the STOL CH 750, and a newly designed tail with a separate vertical fin and rudder, rather than the all-flying rudder of the STOL version. The model is optimized for cross-country speed rather than STOL capabilities, although the specified 350 ft (107 m) ground roll of the Cruzer qualifies as [[Engineering:STOL|STOL]] by most definitions. It mounts wheel pants as standard (although these may be removed and larger wheels installed) and the prototype is powered by a {{convert|130|hp|kW|0|abbr=on}} ULPower UL350is fuel injected engine, although other engines in the {{convert|100-160|hp|kW|0|abbr=on}} range can be used.<ref name="Niles12Apr13">Niles, Russ.

;STOL CH750 Super Duty
:This model introduced greater carrying capacity and climb capabilities. It can be powered by engines with a range of {{convert|150|to|230|hp|kW|0|abbr=on}}, with the prototype powered by a {{convert|205|hp|kW|0|abbr=on}} Aero Sport Power IO-375 powerplant, which gave a cruise speed of {{convert|105|mph|km/h|0|abbr=on}} and a rate of climb of 1350 fpm (6.9 m/s). Gross weight is {{convert|1900|lb|kg|0|abbr=on}}, with a typical empty weight of {{convert|1100|lb|kg|0|abbr=on}}.<ref>{{cite web|url=http://www.zenithair.net/introduction-ch-750-super-duty/|title=Zenith Aircraft Company|website=zenithair.net|access-date=30 March 2019}}</ref>
