"25 BALANCING THE SUPER STICK
An important part of preparing the aircraft for flight is
properly balancing the model. Don’t inadvertently
neglect this step. The recommended C.G. (Center of
Gravity) location for the first flights with the Super
Stick is 1/8" behind the main spar of the wing (the
main spar spans the length of the wing underneath the
back edge of the wing sheeting).
If necessary, add weight to either the tail or nose until
the correct balance is achieved. Stick-on weights are
available at your local hobby shop and work well for
this purpose."
