Parts Don with the Ultimate Linkage
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.  

“From its fast, 20-hour assembly to the uniquely simple and secure method of wing attachment, our Ultimate Biplane ARF makes it as easy as possible to enjoy biplane aerobatics in a BIG way!”

- Don Anderson, Founder
  Great Planes Model Manufacturing

  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.

Engine Landing gear Wing
An ideal engine match for your Great Planes Ultimate Biplane ARF is the O.S.® 1.60 FX — available with or without muffler.   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.   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.

Wing Tension Wing
    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 setscrew to lock it in place - avoiding the difficulty of cutting wire to a length that will be tight enough, but not too tight.
