The parts fit, design, and wood selection of the Ultimate Biplane ARF are
exceptional...and it requires only as little as 20 hours to assemble! The
lightweight construction, due in part to strategic use of lightening holes,
provides an excellent power-to-weight ratio for outstanding 3D performance.
Light and strong, the airfoil-shaped, molded composite landing
gear resists spreading under the model's weight. Expertly
applied MonoKote® covering, a factory-painted fiberglass cowl
and wheel pants contribute to spectacular looks. Includes
spinner and hardware that's custon-engineered for giant-scale.
An ideal engine match for your Great Planes Ultimate Biplane
ARF is the O.S.® 1.60 FX — available with or without muffler.
Achieving the proper tension on the flying wires is easy, because of
special fittings that mount in the horizontal and vertical stabilizers. After
threading the wire through the fitting, you simply tighten a set screw to
lock it in place - avoiding the difficulty of cutting wire to a length that will
be tight enough, but not too tight.
Rather than using a linkage between the top and bottom wings to operate
the ailerons, each of the Great Planes Ultimate Biplane ARF's four
ailerons is actuated by its own servo — resulting in clean, scale-like
looks; fast, dependable response; and maximum maneuvering muscle.
The Ultimate Biplane ARF's unique method of wing attachment
requires no special tools and eliminates the chance of losing screws.
Two thumbscrews are permanently installed in the top and bottom of
each strut. To secure the wing panels in place, you simply insert the
strut and turn its built-in thumbscrews.
