Focke Wulf FW 44 ARF 11
Landing gear has scale oleo, rubber
dampened, spring action as the full size
aircraft. Right hand side aluminum
panel removed.
The elevator is actuated with the joy-stick and
the rudder with the rudder bar.
Assembly of wing panels
1. Push the lower wing halves into the holes
in the fuselage.
2. Attach the upper wing using the 4 Allen
6-32 screws supplied (note that the front screws
are longer and the rear screws shorter). Connect
the aileron bellcranks with push rods to the servo
in the fuselage. Install the link wires between the
lower and upper ailerons. Adjust length so that
all ailerons are neutral. Check the movement of
the ailerons. We recommend that you attach the
aileron pushrods in a manner, acheiving
differential throw of the aileron. Attach the flying
wires in place. Attach the landing wires in place.
3. Install the interplane struts. Secure with
2 mm screws and 2 mm lock nuts. Note that the
rear strut is adjustable at the attachment point
in the lower wing. By turning the screw up or
down you can adjust the wing outer section
incidence and the wash out of the upper wing.
Landing gear
Install the landing gear by securing the legs
with 3 mm screws and lock nuts. The centre
point schould be attached to the landing gear
support tripod with a 3 mm screw and lock nut.
Install the wheels on the shaft and secure
with the stoppers. This type of landing gear relies
on the spring action of the rubber in the oleo
mounting in the landing gear. This is a very
efficient shock absorber. If worn out the rubber
can easily be replaced with a fresh, longer one.
Balancing
The center of gravity / balancing point
should be approx. approx. 13 cm (5.2")
measured from the leading edge center of the
upper wing. Placing the C/G up to ½" further
forward makes the airplane steadier but limits
the aerobatic capability. Make adjustments if
necessary to suit your flying taste..
Flying
The prototype was flown with a OS .90
4-stroke FS which provides ample thrust. Let the
engine swing a 16x6 propeller if possible. This
gives better thrust outside the big dummy engine
and reduces sound to a more realistic level.
Flying characteristics are very forgiving
and will fly hapily on half trottle. Set the elevator
at zero angle for the first flight but be prepared
to give down elevator if the model climbs out too
steep. During the initial take off run you have to
compensate for the torque with right rudder but
as the speed builds up the rudder is returned to
neutrual. This model should fly of the ground and
not be pulled.
The landing approach can be rather
steep as per prototype but the flare out needs
almost full up elevator. Get the tail down to
maintain directional stability. Remember this
was the mount of many of the German aerobatic
aces.
Happy landings!
