The advantage of this is considerably lighter weight, resistance structural fatigue and corrosion. The wings have a folding option, which require no tools and can be easily done by one person, for trailering and storage. The seats are adjustable, comfortably fitting a 5 foot 5" inch pilot and a pilot over 6 feet tall into the 42 inch wide cabin. The craft uses conventional stick and rudder controls with dual center mounted sticks, dual rudder pedals and dual throttles, with center mounted brake and 2 position flap handle. Ground steering is via a steerable nose wheel, which can be aided with the addition of brakes. Power is supplied by the Rotax 912 series of engines. Cruise comes in at 100 mph at 4400 rpm on the 80 HP Rotax 912. Fuel consumption at this speed is approximately 3 gallons per hour giving the plane a safe range of 450 to 500 miles with the standard fuel tank. The plane lifts off at just over 40 mph with flaps and climb comes in at over 1,000 feet per minute with two on board and full fuel. Stall with the engine running is nearly impossible, as the plane just settles into a gentle mush, with no tendency to drop a wing. On landing the craft with flaps touches down at around 40 mph. The large easy to view instrument panel can be accommodate just about anything a pilot could want to fit in it. The FK9 MK IV is also easily adaptable to both floats and skis. Currently there is one flying unit in the U.S. with two more expected to be ready for delivery by customers by June. |
