Instruction Manual
With the wing attached to the fuselage, all
parts of the model installed ( ready to fly), and
empty fuel tanks, hold the model at the
marked balance point with the stabilizer level.
Lift the model. If the tail drops when you
lift, the model is “tail heavy” and you must
add weigh* to the nose. If the nose drops, it
is “nose heavy” and you must add weight* to
the tail to balance.
*If possible, first attempt to balance the model
by changing the position of the receiver bat-
tery and receiver. If you are unable to obtain
good balance by doing so, then it will be nec-
essary to add weight to the nose or tail to
achieve the proper balance point.
Accurately mark the balance point on the top
of the wing on both sides of the fuselage. The
balance point is located
135mm
back from
the leading edge. 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 loca-
tion we recommend .
