The plane is made from 90% composites with the moving flight
surfaces currently covered in conventional fabric covering material,
but will also be composite in the near future.
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. |
