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.

face.
