Section 13:
Center of gravity
An important part of preparing the aircraft for flight
is properly balancing the model.
Caution: do not inadvertently skip this step!
The recommended Center of Gravity (CG) location for the
your model is 3 / -inch (90mm) back, or 25% of the chord,

from the leading edge of the wing. Mark the location for the
Center of Gravity on the top of the wing next to the fuselage
as shown.
When balancing your model, support the plane inverted at
the marks made on the top of the wing with your fingers or
a commercially available balancing stand. This is the correct
balance point for your model. You might find you may be
required to add a small amount of weight to either the front
or back of the fuselage to achieve the correct balance.
After the first flights, the CG position can be adjusted for
your personal preference.
