4)
Do not turn plane upside down. Only low
wing models should be turned upsidedown for
balancing. Remove this paragraph, it is not
intended for use in the instructions. it is a note
for you.High Wing models must be balanced
upright.
2) Mount the wing to the fuselage. Using a
couple of pieces of masking tape, place them
on the bottom side of the wing
60=mm
back
from the leading edge of the wing at the wing
root.
Accurately mark the balance point on the
botttom of the wing on both sides of the
fuselage. The balance point is located
60 mm
back from the leading edge of the wing at the
wing root. This is the balance point at which
your model should balance for your first flights.
Later, you may wish to experiment by shifting
the balance up to 10mm forward or back to
change the flying characteristics. Moving the
balance forward may improve the
smoothness and arrow- like tracking, but it
may then require more speed for take off and
make it more difficult to slow down for landing.
Moving the balance aft makes the model more
agile with a lighter and snappier ”feel”. In any
case,please start at the location we
recommend .
