Default Zenith STOL CH 701

https://en.wikipedia.org/wiki/Zenith_STOL_CH_701

The Zenith STOL CH 701 and CH 750 are a family of light, two-place kit-built
STOL 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 2018. The CH 750 was first introduced in
2008. The CH 701 was later developed into the four-place Zenith STOL CH 801.

The kit is produced and distributed in the USA 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.

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, an all-flying rudder, large tires,
flaperons and an inverted elevator. Heintz also designed a unique tricycle gear
amphibious float system for the CH 701.

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. The aircraft has also been equipped with the JLT
Motors Ecoyota engine.

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.

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. 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. The CH 750 is designed to comply with
the US Light sport aircraft rules.

Zenith STOL CH 801

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

Variants

STOL CH 701 Original version

STOL CH 701SP
Comes with two standard 10 gal wing tanks, solid aluminum spring gear. Smaller
refinements to achieve a gross weight of 1100 lbs (500 kg).

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.) 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.

CH750 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
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 130 hp
(97 kW) ULPower UL350is fuel injected engine, although other engines in the
100–160 hp (75–119 kW) range can be used.

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 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).
