The Zenith STOL CH 701 and CH 750 are a family of light, two-place kit-built aircraft designed by Canadian 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 in 2011.[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.[2][4]
The kit is produced and distributed in the USA by the Zenith Aircraft Company, 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.
Design and development
Designed for off-runway operations, the all-metal CH 701 has many unique features, such as a high-lift wing with full-span, non-movable leading edge slots, an all flying rudder, large tires, flaperons and an inverted elevator, that contribute to the aircraft's STOL capabilities. 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 two-stroke, the 80 hp (60 kW) Rotax 912UL, the 100 hp (75 kW) Rotax 912ULS and the 85 hp (63 kW) Jabiru 2200 four-stroke powerplants.[4][5]
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][6]
Designed to the Light Aircraft Manufacturers Association of Canada (LAMAC) design standard DS 10141, in its native country of Canada the CH 701 can be built and flown as a basic ultralight, advanced ultralight or amateur-built.[7][8] The CH 701 can be flown under microlight or ultralight rules in several other countries also. American pilots may fly the CH 701 under Light-sport Aircraft rules or as an experimental amateur-built.[2] The CH 750 is designed to comply with the US Light sport aircraft rules.[3]
Operational history
By the fall of 2007 750 CH 701s had been completed and were flying.[2]
Variants
- STOL CH 701
- Base model, introduced in 1986, with a gross weight of 1100 lbs (500 kg).
- STOL CH 750
- Introduced at AirVenture 2008, it has an enlarged cabin with wider doors and is optimized for the 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.)[3][4]

- CH-750 Cruzer
- Introduced at Sun 'n Fun 2013 the CH-750 Cruzer uses a new non-STOL wing and new design tail with a separate fin and rudder. The model is optimized for cross country speed rather than STOL capabilities. It mounts wheel pants and the prototype is powered by a 130 hp (97 kW) ULPower UL350is fuel injected engine, although other engines in the 100 hp (75 kW) range can be used.[9]
