42) Install the bottom wing to the fuselage using the
1/4-20 x 1-1/2" nylon bolts. Take care that the aileron servo wires
are not caught between the wing and the wing saddle of the
fuselage. Attach the top wing to the fuselage by inserting the strut
fittings on the bottom center of the wing into the space between the
cabane struts on the fuselage. Line up the holes in the strut fittings
with the holes in the cabane struts and secure the wing in place
with the provided M3 x 10mm PWA bolts and 3mm lock nuts. Do
not install the interplane struts at this time.
❑
43) Because the Sun Dancer 50 is a biplane configuration, the
incidence of the wings is twice as critical and therefore must be
properly set up to achieve its full flight performance potential. The
following steps require the use of an "incidence meter" to properly
align the wings. Do not attempt to set up this model without the
use of a good incidence meter.
a) Place the incidence meter on the lower wing, and then block
up the back of the fuselage until the incidence meter reads
0
O
of incidence.
b) Remove the incidence meter and move it up to the center of the
top wing. View the top wing from the front to make sure it is at or
very close to horizontal (level). With the top wing in this position,
16
of the fuselage to turn the system on and off. This is actually quite
simple to do. First drill a small diameter hole in the switch lever to
fit a piece of .045" dia. music wire. Drill an exit hole in the side of
the fuselage, lined up with the switch/wire location. Make a 90
O
bend in one end of the wire and insert the short end into the hole
in the switch lever. Insert the wire through the hole in the fuselage
and make another 90
O
bend in the wire, outside of the fuselage
side, giving you a small "handle" to pull and push when activating
the on/off switch.
Besides looking neat, your switch is now
protected from the elements.
FINAL ASSEMBLY:
❑
41) Locate the parts bag containing the ten (10) aluminum strut
attach fittings. Two of these fittings are now installed into the two
pre-drilled holes on the bottom center surface of the top wing.
Screw each fitting in place until the bottom of the fitting just
touches the bottom surface of the wing. Now turn the fittings back
out one full turn until their mounting holes squarely face each wing
tip.
The remaining eight (8) aluminum strut fittings are now installed at
the outer pre-drilled holes on the bottom of the top wing (4
required) and the top surface of the bottom wing (4 required). Just
as described, screw these fittings in place until their mounting lugs
contact the surface of the wing and then back them out one full
turn to orient their mounting holes toward the wing tips, parallel to
the wing span.
MODELER’S TIP: To give your model that professional look,
use a rubber powered nose bearing from Peck Polymers (Part
Number 006) as an exit guide for the switch wire, where it
passes through the fuselage side. This gives the whole thing
a very nice, finished look.
