Section 16: Balancing the J-3 Piper Cub

An important part of preparing any aircraft for flight is properly
balancing the model. Don't inadvertently forget this crucial step.
The recommended C.G. (Center of Gravity) location for the first
flights with the J-3 Cub is 3-1/4" from the leading edge. With
the Saito .50 installed, very little, if any, additional weight will be
needed to balance the model. If you're using a lighter 2-cycle
engine, expect to add weight. Stick-on weights are available at
your local hobby shop and work well for this purpose.
