The Zodiac CH 640 Chris Heintz design is a four-place, low-wing, all-metal kit aircraft. The CH 640 is a conventional four-seater, with a 2 + 2 seating configuration. The prototype aircraft is powered by a 180-hp Lycoming O-360 engine. The design features a fixed tricycle landing gear, large dual gull-wing doors, a wing span of 31.5 feet and an overall length of 23 feet. The Zodiac CH 640 is designed to bridge the gap between utility designs and the fast and expensive composite designs – to make it a practical and useful aircraft for the “average” pilot/builder. The CH 640 has a useful load of 1,000 lbs., making it a true four-seater. Heintz used the Zenith CH 2000 as the basic platform for his new design since the aircraft already boasted a huge cabin area, and the type-certificated design could easily be stretched into a four seater. Starting with a basic CH 2000 fuselage assembly, the CH 640 started to take shape by stretching the cabin area and adding the rear seat. New wings and horizontal tail sections were also developed, and the firewall-forward side was borrowed from the Heintz’ STOL CH 801 design which utilizes the same engine. The new airframe took just three months to put together. The CH 640 has conventional all-metal construction adapted for quick and simple kit construction. Kit parts are supplied ready-for-assembly, using blind rivets extensively. Many of the kit parts are the same design as the production Zenith CH 2000, which is being produced under an FAA production certificate.

The original Zodiac CH 600 was designed by Chris Heintz as a low-cost primary trainer aircraft. The 1984 Zodiac CH 601 HD is the updated model. New improvements to this model include a wider 44-inch cabin and a larger rear baggage compartment. Standard equipment includes wing baggage lockers, hydraulic disk brakes, electric trim tab, and tinted canopy. Designed to meet the requirements of the sport pilot, the aircraft offers great performance and capabilities, and is easy-to-fly with pilot-friendly characteristics, including a low landing (stall) speed. The aircraft has excellent cross-country flying capability as well as short-field performance of well under a thousand feet. The HD (Heavy duty) version is stressed for + or -6G. The S-series speedwing option features a four foot shorter span and a thinner, tapered aerofoil in the outboard section, with a scarfed tip for enhanced dihedral effect. Other options included wing fuel tanks.
A lightened version of the Zodiac CH 601 HD, the basic CH 601 Zodiac model was developed in 1984 specifically for the Advanced Ultralight (AULA) category in Canada and other European countries, where the CH 601 can be used as a trainer and personal aircraft.
Zenith CH-601 NC41013
With a reduced gross weight, this model’s specifications are very similar to those of the CH 601 HD model. With a lighter gross weight (useful load), a lower empty weight is achieved using lighter materials in selected areas. Registered as an advanced ultralight, the basic CH 601 makes an ideal low-cost trainer and personal aircraft. Bubble canopy was standard, but was available with an open cockpit, taildragger, trigear, or twin-float options. As a certified design, factory pre-assembled aircraft were available direct from the manufacturer. As of Oct 1998, 275 kits were sold and 200 built from plans.
The basic airframe kit for the HD cost $12,620, the HDS Super Zodiac basic airframe kit $13,640, and XL Super Zodiac basic airframe kit $15,890, all in 1998.
CH 601 Super Zodiac
Based on the Zodiac CH 601 HD, the Super Zodiac 601HDS features tapered and shortened ‘speed wings’ to achieve a higher cruise speed. The wing span is reduced to 23 feet, and the wing area is lowered to 98 sq. feet, with the airfoil tapering to a 34 inch chord at the wing tips. The speed wings have full-length ailerons for very responsive controls. The Super Zodiac has the same fuselage and tail sections as the CH 601 HD model; the only difference being the outboard wing panels. The outboard wings of the Super Zodiac and the Zodiac CH 601 HD can be interchanged.
CH601XL
Grossing 100 lb heavier than the CH 601, the CH601XL was designed to accommodate larger engines such as the Continental O-200, Lycoming O-235 and Rotax 912s, all in the 100 hp range. The 601XLhas an entirely new wing, 27 ft span, and has the same dihedral from the root to tip because the aluminium spring maingear legs are attached to the fuselage structure. Construction is of 6061-T6 aluminium with pulled rivets. The new wing also has electrically operated flaps, which reduce the span of the ailerons. The XL canopy is forward tipping with gas spring assist, and behind the seats is a 40 lb baggage area. The cabin area is three inches longer than the 601. The flight controls are cable operated. 2009 Price: 64000 EURO With the new wing flaps, stall speed has been kept low for recreational pilots. The XL design is the product of extensive research and development, and the result of professional engineering by Chris Heintz, a leading designer of light aircraft. The modern design makes use of advanced technologies, while using proven design concepts and simple systems for easy assembly and maintenance. A professional design, the structure has undergone a complete and rigorous flight test and design stress analysis, as well as load testing of critical components. The XL has been configured to take full advantage of its increased useful load: New and larger wing tanks offer a larger fuel capacity resulting in superior range and endurance, and the baggage area behind the seat has also been increased. Also with optional wing storage lockers the baggage capacity of this aircraft is quite exceptional. The XL features a new spring main landing gear system. The standard tricycle gear provides effective ground handling and allows for excellent forward visibility while taxiing. This heavy-duty tricycle gear system was chosen as the standard gear configuration as it provides better stability and control on the ground. The Rotax 912ULS 100HP engine offers great performance and is highly recommended for this aircraft as it provides great reliability, and is very efficient and smooth-running. The Zodiac XL prototype model is powered by the six cylinder Jabiru 3300. Lycoming O-235 (116-hp) and Rotax 912S (100-hp) engines have also been installed and flown in the prototype. The XL has been developed with the FAA’s proposed Sport Pilot / Light-Sport Aircraft category in mind, and offers maximum performance and capability possible under the new FAA category.

Designed primarily to satisfy the need for a good cross-country per¬former that falls into the sport plane category, the three passenger Tri-Z can be fitted with medium power engines in the 125-to 180-hp category. With only two persons in the front seats, the rear bench can be covered with 210 pounds of baggage. The Tri-Z easily adapts to floats or taildrag¬ger options and is easy to fly. It has docile handling characteristics.
A CH-300 Tri-Z set a new 3,000-mile non-stop record in July 1978.

With 100 hp the CH-200 will cruise for four hours at 130 mph carrying two passengers and baggage, while 150 hp and an aerobatic option turns the Zenith into a powerful per¬former. (The Zenith is stressed for engines from 85 to 160 hp). First designed and built in 1974. Two ¬place seating is under a sliding canopy in a fuselage formed by four longerons with stiffened skins, blind riveted to longerons. Five bulkheads carry the top skin. The constant-chord wings have a single cantilevered spar with three sections and electronically-operated flaps. One-piece, all-moving, horizontal and vertical control surfaces constitute the tail.

The Mono-Z is a single-place, scaled-down version of the original Zenith first built in 1974. It offers maximum operating economy with VW power at a three gph cruise. Detachable wings leave an 8-foot-wide section for easy road towing, requiring only 20 minutes to install both wings. It is stressed for 9G’s and with 100-hp becomes a powerful aerobatic performer. Engine range from the VW 1600 to 100-hp Continental.
In his spare time, Heintz began to design and build his own aircraft, which he named the Zenith, anagram of Heintz. After a little more than a year’s work, the two-place low-wing Zenith was rolled out and successfully flown on 22 March 1970 as F-WPZY.
Soon after, detailed blueprints and construction manuals of the aircraft were drawn up and offered to the growing number of interested builders and flyers.
Zee Aero (now Wisk), originally under the leadership of Professor Ilan Kroo of Stanford University, developed a proof of concept vehicle with a series of high, vertically-mounted mounted electric propellers. The proof of concept made its first unmanned hover in December 2011, and in February 2014, completed its first transition from hover to forward flight.
