BALANCING.
1) It is critical that your airplane be
balanced correctly. Improper balance will
cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
65 MM BACK FROM THE LEADING EDGE
OF THE WING AT THE WING ROOT.
3) Turn the airplane upside down. Place
your fingers on the masking tape and carefully
lift the plane .
2) Mount the wing to the fuselage. Using a
couple of pieces of masking tape, place them
on the top side of the wing
65 mm back from
the leading edge of the wing at the wing root.
Accurately mark the balance point on the top
of the wing on both sides of the fuselage. The
balance point is located
65 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 .
