THE NEW STOL CH 801-SD
More Wing Span! More tail surface! More Useful Load!
______________________________________________________________________________________________________________
News:
Together with a US-based customer, Zenair is currently building a unique "SUPER STOL" aircraft based on the Heavy-Duty (HD) STOL CH 801. With a top-of-the-line engine (Titan IO-370), Propeller (by Catto), Avionics (by Garmin) and a long list of special features and custom options, this aircraft will also have an advanced new airframe. Expanded in so many ways (Extended wings, Extended elevator, Extended range, Extended weight limits, etc.), we are now designating the aircraft the STOL CH 801-SD ("Super-Duty")...

Design History:
In 2010, Zenair began working with AviaMaster Aircraft (AMA), a small company based in Almaty, Kazakstan, to develop and convert the original all-purpose recreational STOL CH 801 kit aircraft into a highly effective agricultural spray-plane. With AMA’s determination and field-testing capabilities and Zenair’s aeronautical engineering skills and experience, it took less than two years for the new “HD” model to be finalized. In early 2012, Zenair offered the first kit version of the CH 801-HD to North American builders and by the end of the year, the new "HD" model had become the new norm for the all-metal 4-seat CH 801.
 |
Based on the success of the STOL CH-801-HD as a commercial spray plane (a.k.a. the CH-8000), Zenair and AMA then began working on a new and larger version of the aircraft: one that would have an increased gross weight and higher useful load. This exciting new design was tested and operated by AMA throughout 2015/16; This is the aircraft Zenair is now developing into the all-new CH 801-Super-Duty-STOL.
Conceived for more demanding missions and maximum utility, the new and larger STOL CH 801-SD offers enhanced load-carrying capabilities as well as exceptional slow-flight performances while still using simple, proven design concepts for easy assembly, operation and maintenance. |
Note: The CH 801-SD is a re-designed STOL CH 801-HD with a larger airframe and enhanced components (different parts) throughout. There is no "upgrade kit" available to convert an HD model into an SD model. For more information on the Super-Duty design and its availability, contact Zenair directly.
More Wing!
|
The new STOL CH 801-SD design has 4 feet additional wingspan than the lighter "HD" model. That's 2 feet per side, for a total wing area of 189 square feet. This added lifting capability allows the aircraft to carry higher loads, whether passengers or cargo. At lighter loads, the larger wing allows for even more spectacular short take-offs and STOL performances.
|
|
More Tail Area!
|
An extended stabilizer and elevator give the larger and heavier STOL CH 801-SD all the control it needs for slow flight - and the repetitive and often very demanding (extreme) maneuvers used for effective crop spraying. The "SD" model uses the same All-Flying rudder design found on other Zenair STOL models for superior directional/yaw control and remarkable cross-wind capabilities.
|
|
More Useful Load! The 4-seat STOL CH 801-SD offers one of the highest useful loads for any kit aircraft in its category. Originally developed to carry chemicals for crop-spraying, the 1,200 lbs useful load allows for heavier passengers, more baggage or additional equipment. The aircraft can easily be configured or equipped for "specific use" or "special missions".
|
|
Tougher Gear System!
 |
The stock tricycle gear system used on the STOL CH 801-HD has outstanding shock absorbing capability for rough field operation. The one-piece main gear spring on the "SD" model is even beefier and stronger than on the "HD" model. Made of 7075-T6 aluminum (rather than 6061-T6), the aircraft can handle rough field with its regular wheels, or can also be equipped with large tundra tires for extreme environments... The aircraft's tricycle gear system offers rough field capability while providing all the advantages of a tricycle-gear aircraft, such as easy and precise ground handling and superior over-the-nose visibility.
|
Tougher airframe!
|
The STOL CH 801-SD was not just designed for mundane tasks, it was developed by commercial AG pilots who needed a work-horse capable of handling heavy loads and extreme manoeuvres day-in and day-out. The new wings have more ribs, a number of aluminum skins are thicker and the steel-tube cabin frame has also been reinforced. The airframe itself is designed to allow maximum customization by the builder.
|
 |
More power!
|
The STOL CH 801-SD is designed for a wide range of aircraft engines, from 180 to 240 HP. Because it is not designed ‘around’ a specific engine, custom installations by builders are possible, easy and straight-forward.
Propellers can also be customized based on available budget and for desired performance. |
More Fuel!
 |
FUEL SYSTEM: The STOL CH 801-SD is equipped with a pair of 15 US gallon (56 liters) welded aluminum wing fuel tanks, located inside the wing behind the main wing spar. The Extended Range Option doubles the number of wing tanks to four, for a total fuel capacity of 60 gallons (224 liters).
|
Note: the STOL CH 801-SD is not available as a "plans-only" project; it is a kitplane for which standard and advanced kits can be available from Zenair. Comprehensive assembly instructions and manuals will be provided with each kit sold. For more information, contact Zenair!
