[2], Test flying the WT-11 was carried out following the first flight on 12 December 1982 at Wizard Lake, Alberta, by company chief test pilot Dennis Maland. Kit/Plans: Company testing showed take-off distances of about 300 feet (91 m) on the water and no need for additional vertical surfaces to be added. The WT-11's wings are removable by two people in 15 minutes. The tail surfaces use a similar sealed-gap system, utilizing seamless transitions from the fixed fin and horizontal stabilizer to the movable rudder and elevator. [2], The wing is a two-spar design, supported by a "V" strut and jury struts. The new model has a completely new landing gear and many other improvements over the 2S and was built by Canadian Ultralight Manufacturing, which ASAP acquired. Seeing the opportunity to step in and provide parts for the fleet he founded Aircraft Sales and Parts (ASAP) in 1988, in Vernon, British Columbia.

Fax: 320-260-1767 It isn't hard to control, and many aerobatic planes are similarly unstable, but it is an airplane that needs to be flown positively at all times and so would make a less than ideal trainer or plane for a low time pilot. In assessing the handling of the 2S one reviewer wrote: Pitch proved to be neutrally stable – it just stayed where it was put. The price for a WT-11 in 1984 was Can$7995 (US$6395). The aircraft has a very low power off sink rate of about 350 fpm (1.78 m/s). Some pages or functions may not work correctly.

[2][6][10], The company design goals for the WT-11 were:[2]. EAA.Org is currently undergoing some maintenance. [3][4], In 1987 the WT-11 was redesignated as the Chinook 1S (1 Seat) by the company to align its nomenclature with the later two-seat Chinook 2S model. The covering includes zippers to facilitate inspection. [5], In 1993 a 64 hp (48 kW) Rotax 582-powered Chinook Plus 2 on skis and Full Lotus Floats was used by the National Geographic Society in filming a television special about marine mammals in the Canadian Arctic. Chinooks have been soared power-off for long duration flights. Over 850 in total have been completed and flown and kits remain in production in the 21st century. The pitch and yaw axes both exhibit notable negative static stability and the aircraft likes to diverge from straight and level flight in both pitch and yaw. [8][11][15], The Chinook Plus 2 [with the 912 engine] is definitely not a beginner's airplane and [ASAP factory demonstration pilot] Larry [Williams] reports that students take quite a bit of extra time to adapt to its handling. The ailerons were the same. [2][6], The factory claimed that construction time from the assembly kit was 100 hours for a first time builder. Type: Tailwheel, Mono High Wing with full span flaperons (detachable), Seats: 2 in tandem (cockpit size is 39 in. [18], Aircraft of comparable role, configuration, and era, "Saved from Extinction! The glide ratio is 10:1 at 35 mph (56 km/h) and minimum sink is 350 fpm (1.78 m/s) at 32 mph (51 km/h). Users may experience limited site functionality. Weighing slightly over 3 lbs, it’s also a self-supporting freestanding tent that can be set up just about anywhere, on wooden tent platforms, rock, sand, and snow without having to be staked to the ground first. Telephone: 320-259-6411 Conversion kits for the existing aircraft fleet were made available. [8], The Plus 2 initially had a gross weight of 900 lb (408 kg), but this was progressively increased to its present 1,050 lb (476 kg). The aircraft was flown in 35 mph (56 km/h) surface winds safely. The 35 hp (26 kW) Rotax 377 engine became quickly available as an option to give the aircraft more power on floats. The yaw axis was interesting – it remained slightly stable with feet on the pedals, but with feet off and the rudder removed from the fin effect as it floated, the aircraft was unstable. The structure was static load tested to +6/-3 g. The fuselage is built on a 4 in (10 cm) central "spinal" tube that supports the cockpit and the tail surfaces. The ailerons were originally designed to be "gapless", with the wing's Dacron covering extending over the ailerons. [17], The Chinook WT-11 design won Reserve Grand Champion at AirVenture in 1983 and again in 1984. Capital Air Sports, Inc. wide and 104 in. Releasing the stick returns the Chinook to flying with little altitude loss. Fuel capacity with up to four fuel tanks, with options for tundra tires, skis or floats, this aircraft can literally take you where no other aircraft can in its class. [2][6], Initial results showed that with the 28 hp (21 kW) Rotax 277 engine the aircraft would sustain level flight at low throttle settings and would cruise comfortably at 50 mph (80 km/h). They should be easy to build and fix.

The fuel tank was relocated from the fuselage to both wing struts as aerodynamically-shaped plastic tanks, where they are visible in flight and the fuel level can be quickly determined. Initially ASAP concentrated on supplying parts, but with assistance from the University of Alberta Holomis redesigned the aircraft. [2], The WT-11 was designed to comply with the then-new US FAR 103 Ultralight Vehicles category, including the maximum 254 lb (115 kg) empty weight. The airfoil was developed by Dr Dave Marsden at the University of Alberta and is designated as the UA 80/1. The heavier engines, particularly the Rotax 912, have been noted as changing the aircraft's handling characteristics and making the aircraft less stable in pitch and yaw. The cockpit is of a unique pentagonal cross-section that provides a very wide 38 in (97 cm) cabin at hip level. [2], Cross wind testing showed the aircraft was controllable in winds of 20 mph (32 km/h) at 45 degrees and 15 mph (24 km/h) at 90 degrees. Email: leon@paratrike.com The Birdman Chinook is a family of single and two-place, pusher configuration, high-wing ultralight aircraft that was first flown on 12 December 1982 and produced by Birdman Enterprises of Edmonton, Alberta, Canada starting in 1983. "[3][10][11], The construction of the 2S is similar to the WT-11, with the wingspan increased by 2.0 ft (0.6 m) and the same fuselage as the WT-11, with the second seat where the WT-11's baggage area is located. [5], In August 1983 test pilot Dennis Maland flew a WT-11 with the standard Rotax 277 engine to a height of 18,500 ft (5,639 m). But an Ultralight should be affordable by many people, so it shouldn't become expensive. The wings, for example, can't be complicated. [2][3][4][5][6], The Chinook design has evolved through several models over time and has been produced by two companies. The website is currently undergoing maintenance. Fuel capacity with up to four fuel tanks with 22 gallons usable fuel, with options for tundra tires, skis or floats, this aircraft can literally take you where no other aircraft can in its class. A near-vertical pitch resulted in a clean stall, with a smooth pitch forward and recovery to level flight with no wing drop tendency. The wing has internal lift and drag bracing wires.

[2], The remaining flight testing established the service ceiling as 15,000 ft (4,572 m) and the absolute ceiling as 18,400 ft (5,608 m). The Chinook Plus 2 typically equipped with a Rotax 582 (65 HP) and is the gold standard in short/soft field capability, useful load, ruggedness, reliability, range and cockpit size with unlimited visibility. Email: info@capitalairsports.com In 1986 the company abandoned the "gapless" aileron design and moved to a more conventional separate aileron. [2], The WT-11 was tested on fiberglass floats, mounted close to the fuselage. [2], The landing gear is of conventional configuration, with bungee suspension, giving good rough field capabilities. With the 28 hp (21 kW) Rotax 277 single cylinder, two stroke powerplant the aircraft has a factory standard empty weight of 250 lb (113 kg). What started as a handful of passionate enthusiasts has developed into a major force—and a significant component—of the aircraft industry. Maland rated the rudder and elevators as "very responsive" and the ailerons as "less sensitive but good", with roll rates from 45-45 degrees of 3.5 seconds at cruise speed. The upper cockpit tubing curves down to the aircraft's nose at a ratio of 3:1 to provide a compromise between internal cockpit space and streamlining and gives the Chinook its distinctive profile. Two Place Chinook Plus 2 – 2 Stroke The standard in light sport bush planes! Canada [2][10], The aircraft is constructed entirely from 6061-T6 aluminium tubing, bolted together with aircraft-grade AN hardware and covered with 3.9 oz/yd² (132 g/m²) Dacron. [5], In November 1984 Jack Hughes flew a WT-11 across the width of Australia from Orange, New South Wales to Perth, Western Australia, in 14 days and 49 flying hours, a distance of 2,050 nmi (3,797 km). [3][7][8][9], The first Chinook model introduced was the single-seat WT-11, which entered the market in 1983. [ 1] The US Defense Security Cooperation Agency released details of the proposed sale on the 19th of this month. Designer Talanczuk stated his own design intentions: An Ultralight is not only a fun machine, it should also be usable for utility purposes —— training, fishing trips, crop-spraying and even for freight carrying. [12], The factory claims that a first time builder can complete the Chinook Plus 2 in 220 hours of labour. The standard in light sport bush planes! PO Box 995 The ultimate in light sport bush planes, in its class! Website: http://www.paratrike.com. Aircraft Sales & Parts In general, the plane's handling is quite pleasant despite, or perhaps because of, its unorthodox shape. [11], With the four-stroke HKS 700E engine the Plus 2 has a top speed af 90 mph (145 km/h) and a high cruise of 80 mph (129 km/h), with a 65 mph (105 km/h) economy cruise, burning only about 2 US gal (8 l) per hour, giving a five-hour endurance with standard tanks.
