Temporarily tape varying amounts of lead weight at your desired positions, moving a
little forwards and backwards, and keep re-checking the balance point until the correct
balance is achieved. You’ll typically require between 100 and 200 grams of lead in the nose.
However, it’s the point at which it balances that is critical not the amount of lead used to
achieve this. Don’t be afraid of adding the necessary weight and don’t try and fudge the CG
measurement and think you’ll get away with it!
144.
Once
you
have
accurately
determined the amount of lead needed for
correct balance and the exact location of
where it needs to be placed, make cavities
in the foam to accommodate it. Cut from
the bottom surface and stop short of going
through to the top surface. Secure the nose
weight and reinforce the surrounding area
by covering with a patch of filament tape.
145.
Re-check the CG to make sure it’s
exactly 185mm (7 1/4”) back from the
nose. Adjust if necessary.
FINAL COVERING
146.
Spray the nose area on the bottom surface of the wing with spray adhesive, masking
off the area already covered, and let dry for about 5 minutes.
147.
Continue applying the coloured covering tape from where you finished previously,
working your way forward until completely covered.
148.
Lay strips of the coloured covering tape along the leading edge of each wing panel
so that half of the width is on the top surface and half on the bottom surface. Split and
overlap the tape at the panel joins and split and wrap around at the noses and wing tips.
149.
Apply trims, stripes and/or other decorations as desired.
150.
The included computer-cut vinyl “Skua” sticker has both a backing and a “fronting”.
To apply, peel the sticker of its yellow backing and press it down firmly in the desired
location. Then carefully peel off the transparent “fronting” leaving the cut-out lettering in
place.
FINAL SETUP
151.
Turn on your radio equipment and re-check that everything is functioning correctly
and that the elevons are moving in the correct direction. When viewed from the rear, both
elevons should move up when your transmitter’s elevator stick is pulled back for “up”
control and both should move down when the elevator stick is pushed forward for “down”
control. When your transmitter’s aileron stick is moved to the right for “right roll” control,
the right elevon should move up and the left elevon should move down, and when the
aileron stick is moved to the left for “left roll” control, the left elevon should move up and
the right elevon should move down.
152.
Re-check the neutral position of the elevons. Their bottom surface should form a
straight line with the rear half of the foam section of the wing, measured mid-span.
153.
Adjust the elevons’ throw. Too much movement and the glider will become hard to
control, easier to stall and generally not very fun to fly. Too little movement and the glider
