The **Zenith STOL CH 701** and **CH 750** are a family of light, two-place [kit-built](/source/Home-built_aircraft) [STOL](/source/STOL) aircraft designed by Canadian aeronautical engineer [Chris Heintz](/source/Chris_Heintz_(aeronautical_engineer)) through his [Midland, Ontario](/source/Midland%2C_Ontario), based company, [Zenair](/source/Zenair). The CH 701 first flew in 1986 and the design is still in production.[1][2] The CH 750 was first introduced in 2008.[3] The CH 701 was later developed into the four-place [Zenith STOL CH 801](/source/Zenith_STOL_CH_801).[2][4]

The kit is produced and distributed in the US by the [Zenith Aircraft Company](/source/Zenith_Aircraft_Company) of [Mexico, Missouri](/source/Mexico%2C_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](/source/Czech_Aircraft_Works) (CZAW) from 1992 until 2006, when the license agreement was ended.

## 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 [leading edge slots](/source/Leading_edge_slot), an all-flying [rudder](/source/Rudder), large tires, [flaperons](/source/Flaperons) and an inverted [elevator](/source/Elevator_(aircraft)). Heintz also designed a unique tricycle gear amphibious float system for the CH 701.[4]

Standard engines used are the 64 hp (48 kW) [Rotax 582](/source/Rotax_582) [two-stroke](/source/Two-stroke), the 80 hp (60 kW) [Rotax 912UL](/source/Rotax_912UL), the 100 hp (75 kW) [Rotax 912ULS](/source/Rotax_912ULS) and the 85 hp (63 kW) [Jabiru 2200](/source/Jabiru_2200) [four-stroke](/source/Four-stroke) powerplants.[4][5] The aircraft has also been equipped with the [JLT Motors Ecoyota](/source/JLT_Motors_Ecoyota) engine,[6][7] as well as popular 4 cylinder Continental engines (A-65/C-85) which Zenith still offers an engine mount for.[8]

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.[4][9]

Designed to the Light Aircraft Manufacturers Association of Canada (LAMAC) design standard DS 10141, in its native country of [Canada](/source/Canada) the CH 701 can be built and flown as a [basic ultralight](/source/Basic_ultralight), [advanced ultralight](/source/Advanced_ultralight) or amateur-built.[10][11] The CH 701 can be flown under [microlight or ultralight](/source/Ultralight_aviation) rules in several other countries also. American pilots may fly the CH 701 under [Light-sport Aircraft](/source/Light-sport_Aircraft) rules or as an experimental amateur-built.[2] The CH 750 is designed to comply with the US [Light sport aircraft](/source/Light_sport_aircraft) rules.[3]

## Operational history

By the fall of 2007, 750 CH 701s had been completed and were flying.[2] 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.[12]

## Variants

**STOL CH 701**
- Original version. 960lbs gross and 10 gal header tank. steel spring gear and Rotax 503.[13]

**STOL CH 701SP**
- Comes with two standard 10 U.S. gallons (38 L; 8.3 imp gal) wing tanks, solid aluminum spring gear. Smaller refinements to achieve a gross weight of 1100 lbs (500 kg).[14]

**STOL CH 750**
- Introduced at [AirVenture](/source/AirVenture) 2008, the STOL CH 750 has an enlarged cabin with wider doors and is optimized for US [Light Sport Aircraft](/source/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.)[3][4] The STOL CH 750 was also to be factory-built by [AMD](/source/Aircraft_Manufacturing_and_Design) as a [Special Light Sport Aircraft](/source/Special_Light_Sport_Aircraft) but as of 2014 is listed by the FAA as no longer produced as an SLSA.[15]

CH750 Cruzer

**CH 750 Cruzer**
- Introduced at [Sun 'n Fun](/source/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 [STOL](/source/STOL) by most definitions. It mounts [wheel pants](/source/Wheel_pants) as standard (although these may be removed and larger wheels installed) and the prototype is powered by a 130 hp (97 kW) [ULPower](/source/ULPower) UL350is fuel injected engine, although other engines in the 100–160 hp (75–119 kW) range can be used.[16][17][18]

**STOL CH750 Super Duty**
- This model introduced greater carrying capacity and climb capabilities. It can be powered by engines with a range of 150 to 230 hp (112 to 172 kW), with the prototype powered by a 205 hp (153 kW) [Aero Sport Power IO-375](https://en.wikipedia.org/w/index.php?title=Aero_Sport_Power_IO-375&action=edit&redlink=1) powerplant, which gave a cruise speed of 105 mph (169 km/h) and a rate of climb of 1350 fpm (6.9 m/s). Gross weight is 1,900 lb (862 kg), with a typical empty weight of 1,100 lb (499 kg).[19]

**Nuncats Sky jeep**
- Electric-powered derivative of CH 750, that was first flown in January 2023.[20][21][22]

## Operators

- [India](/source/India)

- [Indian Air Force](/source/Indian_Air_Force) - ordered 85 aircraft, with options for a further 48 for use by the [National Cadet Corps](/source/National_Cadet_Corps_(India)) with 25 in service by February 2001.[23]
