Your Ultimate 40 is not a toy, but rather a sophisticated,
working model that functions very much like a full size
airplane Because of its realistic performance, the
Ultimate 40, if not assembled and operated correctly,
could possibly cause injury to yourself or spectators and
damage property.
If this is your first biplane model, we recommend that you
get help from an experienced, knowledgeable modeler with
your first flights. You'll learn faster and avoid risking your
model before you're ready to take the controls for yourself.
For information on flying clubs in your area, you can
