An important part of preparing the aircraft for flight is
properly balancing the model. This is especially important
when various engines are mounted.
Caution
: Do not inadvertently skip this step!
The recommended Center of Gravity (CG) location for
your model is at the center of the wing tube. The correct
measurement for this is 7

-inch (191mm) measured
back from the leading edge of the wing at the root rib.
Mark the location of the CG onto the bottom of the wing
using a felt-tipped pen. With a helper, lift the aircraft with
your index finger at the location marked on the wing. If the
nose of your aircraft hangs low, add weight to the rear of
the aircraft. If the tail hangs low, add weight to the nose
of the aircraft. Stick-on weights are available at your local
hobby store and work well for this purpose.
The center of gravity can also be measured at the wing tip
by measureing forward of the hinge line 3
