Design Detail







The new STOL CH 750 offers roomy two-place side-by-side seating in an ergonomically designed  cabin. The cabin interior is designed to provide maximum comfort for two typical large adults. Oversized swing-up doors allow easy "slide-in" access to the cabin from both sides. 


Each seat position is adjustable for a perfect fit.  There are three standard available seat positions, at two inch increments.  Additionally, the rudder pedal position can be set by the builder of the kit for optimum positioning.  The standard kit includes the seat frame but no cushioning (padding) or upholstery is included.
    The full domed bubble doors / windows provide both added width to the cabin and amazing visibility to both pilot and passenger.  The doors are hinged at the top, and equipped with locking door handles.  Each door is domed 4 inches (10 cm.) to provide maximum additional cabin space.  With the domed bubble doors cabin width is an amazing 50 inches! (1.27 m.).
The full bubble door provides outstanding side and downward visibility 
The cabin is fitted with a large instrument panel and dual controls accessible from both the left and right seats. The standard center-mounted control column (stick) can easily be operated from either side, and does not limit visibility of the instrument panel. Throttle controls are mounted on both sides of the panel for easy access.  
The large panel measures about 32 inches (800 mm.) across by nearly 11 inches (275 mm.) tall in the center to allow for custom avionics installations, and is ideally suited for modern glass panel installations.

Superior Forward Visibility (STOL CH 701 shown)
Designed for superior forward visibility 
VISIBILITY: Unlike other high-wing designs, the STOL CH 750's wings are positioned above the cabin and fuselage to provide pilot and passengers with superior visibility. The "Above-Cab" wings taper at the wing root to maximize upward visibility while also providing superior side visibility, as the wings are located above the pilot's head. 
Superior Visibility
Designed for superior visibility 
As all seasoned bush pilots will confirm, off-airport operations require an aircraft with superior visibility - for operations in tight areas and to allow the pilot to choose suitable landing areas.  The large "wrap-around" windows and "Above-Cab" wings allow unparalleled visibility.  The tricycle gear configuration also allows excellent forward visibility while on the ground - crucial when operated in off-airport fields.

The standard tricycle gear also allows for excellent forward visibility while taxiing - an important consideration when operating the aircraft in off-airport environments. The heavy-duty tricycle gear system was chosen as theCabin Angle / Rotation standard gear configuration for the STOL CH 750 to meet the needs of today’s pilots: Most pilots are not experienced ‘taildragger’ pilots, and a tricycle gear provides better stability and control on the ground.

The STOL CH 750 uses a high tail configuration to allow easy rotation of the aircraft to achieve high lift during take-offs and landings. In a tailwheel configuration this requires a tall and awkward main gear to achieve the same high angle of attack (see illustration).

Furthermore, the tricycle gear allows for a level cabin area – this makes loading and unloading the aircraft much easier than with an inclined cabin.

In a tricycle gear configuration, the wing is at a neutral angle of attack while the aircraft is on the ground, as opposed to a maximum lift angle with a taildragger. Tailwheel airplanes are thus more susceptible to ground wind conditions while taxiing or even while parked outdoors.

Main gear spring The STOL CH 750 utilizes a heavy duty gear system developed specifically for off-airport operation. The main gear comprises of a simple single-piece aluminum spring leaf which is bolted to the bottom of the fuselage. The single carry-through main gear provides double cantilever deflection. The main gear is fitted with large treaded tundra tires, with independent hydraulic disk brakes.

While it’s not the lightest gear system around, it provides excellent rough-field capability Nosegearwhen combined with large tires, and is very durable, simple and virtually maintenance-free.  The main gear is fitted with 8.00 x 6 wheels and 16-inch treaded tundra tires, with independent hydraulic disk brakes.

The nosewheel strut uses a single heavy-duty bungee for shock absorbency. The nosewheel is steerable, with direct linkage to the rudder pedals for very effective and responsive ground handling and tight turns. The main wheels are equipped with independent hydraulic disk brakes.

The STOL CH 750's gear has been developed specifically for off-airport use. The direct linkage steerable nosewheel, plus differential braking, provide remarkably precise ground handling and steering.

Float operation FLOATS (option): ZenairTM all-metal floats are ideal for use on the STOL CH 750, and may easily be rigged to the aircraft. The floats are mounted on a monoleaf main spring for retained shock absorption on water. New amphibious floats offer capability to operate from both land and water: The amphibious floats feature retractable main wheels (pneumatically activated), and a unique retractable single steerable nosewheel.

This option will be available in the near future.



A short take-off and landing (STOL) aircraft must be able to fly at low controlled speeds, yet it must also offer acceptable cross-country (cruise) performance. The challenge is to design a wing with a high lift coefficient so that the wing area is as small as possible, while allowing for take-off and landing speeds that are as low as possible. Short wings make the aircraft easier to taxi, especially when operating in an off-airport environment with obstructions. They also allow for better visibility, and require less space for hangaring, while also being easier to build and stronger (less weight and wing span to support).


The STOL CH 750 uses a special airfoil design to achieve very high lift, low stall speeds, and high strength. A thick wing, full-length leading-edge slats and trailing edge ‘junker’ type flaperons develop a maximum wing lift coefficient of 3.10, while maintaining a short wing-span – for maximum strength and ground maneuverability.

The stall of the wing occurs at the highest lift coefficient on an airfoil, when the airflow can no longer go around the airfoil’s nose (leading edge) and separates from the upper wing surface. Conventional trailing-edge wing flaps help delay the stall to a higher lift coefficient, but only with limited effectiveness.  However, by combining the use of trailing-edge flaps with leading-edge slats, the wing's lift coefficient can be effectively doubled if used on the full span of the wing.

Leading-Edge Wing Slats:
What Are They and How Do They Work?

STOL WingThe leading edge slats allow the aircraft to fly at a high angle of attack (lower speed) by accelerating the air between the slat and the wing (venturi effect). The leading edge slats allow for steep climb angles of up to 30-degrees. For maximum reliability and to keep construction simple, the leading edge slats are engineered to remain in a fixed position in all flight attitudes, and do not retract (in level flight, the fixed leading edge slats have minimal effect on cruise). The full-length flaperons act as both full-span ailerons and full-span flaps. The flaperons have their own airfoil, and are hung below the wing trailing edge to supply them with fresh undisturbed air for maximum control effectiveness even at low speeds.

Leading edge slats prevent the stall up to approximately 30 degrees incidence (angle of attack) by picking up a lot of air from below, where the slot is large and accelerating the air in the funnel shaped slot (venturi effect) and blowing this fast air tangentially on the upper wing surface through the much smaller slot. This effectively "pulls" the air around the leading edge, thus preventing the stall up to a much higher angle of incidence and lift coefficient.

STOL CH 801 Wing Design

The disadvantage of leading-edge slats is that the air acceleration in the slot requires energy (it creates additional drag). While many STOL designs utilize retractible leading-edge slat devices, the additional weight, complexity, reliability issues and cost of such systems minimize their feasibility for use in light aircraft and their overall effectiveness.

At the wing tip, the STOL CH 750 design utilizes ‘Hoerner’ tips to maximize the wing’s effective lift area and to minimize wing tips vortices. Hoerner wing tips provide the largest effective span for a given geometric span or a given wing weight. Hoerner Wing Tip

The wings are braced by dual steel wing struts, and are bolted to the fuselage at the cabin frame with four bolts for easy wing attachment and removal.

Superior visibility

ABOVE-CAB WINGS: The aircraft wings are positioned above the cabin and fuselage - this allows for excellent horizontal visibility as the wings are located above the pilot’s head to provide pilot and passenger with superior visibility. In addition, the wings taper at the wing root to meet the ‘skylight’ top window – maximizing upward visibility, a feature especially useful in steep turns. While providing great visibility, the ‘above-cab’ wing design minimizes the frontal area of the aircraft to reduce drag, while also allowing the airflow to travel undisturbed from the propeller to the tail sections – further maximizing slow flight control of the aircraft.

STOL CH 701 Tail

The STOL CH 750 tail sections are designed to provide maximum effectiveness (control) at slow speeds and at high angles of attack.

The aircraft designs feature an all-flying vertical tail (rudder) section for excellent effectiveness and control, especially at low speeds. The all-flying rudder provides responsive rudder control, while also minimizing weight and complexity (there’s only one vertical tail section). Two rudder bearings bolt to the rear fuselage to fix the rudder to the fuselage. STOL Rudder (top view)

STOL CH 701 ElevatorThe horizontal tail sections are made up of the elevator and the stabilizer. Both these sections are unique and developed specifically for maximum effectiveness at low speeds and at high angles of attack.The stabilizer is an inverted airfoil section to maximize downward lift to help achieve high angles of attack required for short take-off and landing performance.The elevator is an actual airfoil section, and provides a ‘virtual venturi’ effect when deflected down, as illustrated below.The unique tail sections provide maximum effectiveness for short take-off and landing performance – while also minimizing the actual size of the tail sections.

The STOL CH 750 makes use of highly engineered design features for excellent STOL performance, and importantly, responsive control at low speeds. While many aircraft designs often boast a low stall speed, many of these same designs have minimal control effectiveness at these lower speeds.

Maximum maneuverability

The STOL CH 750's large effective control surfaces provide excellent controllability at very low flying speeds - a necessity for effective short take-off and landing performance - while being very light and balanced.
