4. Push the wing halves into the holes in
the fuselage.
5. Attach the upper wing wires by insering
the screws in the upper pylon ans securing them
with the 2 mm nuts. Install the lower (flying) wires
and secure the kwick-links.
6 Install the upper wing warping wires and
make sure that they ryn freely through the pulley.
Now attach the lower wing warping wires and
make sure that they make half a loop on the
pulley. Check the wing warping with the warping
actuator.
7. Install the wheels on the shaft and secure
with the stoppers.
Balancing
The center of gravity / balancing point
should be approx. 4" = 10 cm from the leading
edge of the wing. Make adjustments if
necessary.
Flying
It is advisable to fit an engine that does
not protrude to far forward or some alterations
have to be made in the fire wall.
Let the engine swing a 14x4 propeller if
possible. This gives better thrust outside the big
cowling and reduces sound to a more realistic
level.
Flying characteristics are very forgiving
but the aerobatic manoeuvers limited. Set the
elevator at zero angle or at the same angl as the
wing, for the first flight but be prepared to give
down elevator if the model climbs out too steep.
This model should fly of the ground and not be
pulled by the propeller.
Ground handling, taxiing, on hard surface
is difficult in anything but calm weather, because
the model will weather-vane into the wind.
Take-off should be done straight into the
wind and the take-off run is relatively short. Make
corrections with elevator and rudder. The wing-
warping during take-off is slow and not so
effective but in flight responsive enough. Turns
should be executed using both wing-warping and
rudder.
Use gentle handling during approach and
make the landing straight into the wind. On the
ground, taxing, unless very calm weather,
should only be attempted with assistance at the
wing tips (as per prototype). Note that the gli-
ding ratio with the engine throttled back, is very
steep. Aeroplanes from this period usually had
a very steep approach for landing.
