Super Sport (oz16531)

About this Plan

Super Sport. Radio control sport model. Wingspan 45 in, wing area 290 sq in.

Discontinued kit from SIG.

Quote: "The Super Sport is an easy to build 3-channel sport model designed with stable and docile flight characteristics tailored to the 'Sunday flyer'. Although it is not recommended as a trainer, it can be handled by relatively inexperienced pilots with a low number of RC flying hours.

Engines from .09 through .15 cu in are ideal for the Super Sport.

For best results, we recommend that you install 3 channel radio equipment in your Super Sport to operate the rudder, elevator, and engine throttle. Or you can install 4 or more channel equipment and use only 3 of the channels (see RADIO INSTALLATION section on page 10). The fuselage is large enough to carry a standard size battery pack and servos.

1 or 2 channel radio equipment could also conceivably be used in the Super Sport but with much less flexibility in control (rudder and elevator control only with 2 channels, and rudder control alone with 1 channel equipment). We DO NOT RECOMMEND 1 or 2 channel operation except by fliers who are well experienced with that type of limited control.

FOAM WING INSTRUCTIONS: IMPORTANT NOTE: For extra strength, two strips of 3 /4 in wide 'Filament Tape' should be applied spanwise across the bottom of the wing as shown. (See SIG catalog for 'Nylon Filament Tape', SH-571, 3/4 in x 18 ft roll.) If you paint your wing as outlined further on in the instructions, do not apply the tape until after the painting is complete and dry. Patches of filament tape can also be put around the trailing edge of the wing for reinforcement at the points where the wing hold-down rubber bands will be located. Other brands of non-stretchable, tear-resistant tape (such as 3M 'Scotch Filament Tape') would also be satisfactory.

Do not let solvent base model cement, dope or fiberglass resin come in contact with the foam wing. These products will all melt foam on contact. Epoxy glues may be used on the wing if repairs become necessary.

FINISHING THE FOAM WING: The wing is fuel resistant and can be left unpainted. However, this is not recommended as painting will greatly increase the life of the wing. The wing of the prototype model was painted with SIG PLASTENAMEL. This paint is ideal for the Super Sport wing as it is completely compatible with foam and provides a glossy and fuel-proof finish.

First use a sanding block with 250400 grit sandpaper to remove any mold flash from the leading and trailing edges of the wing. Avoid sanding too long or too hard in one spot and changing the shape of the airfoil. Next very lightly sand over the entire wing surface with very fine 400-600 grit paper to knock off the tiny molding marks. On the prototype, after sanding the entire wing was painted overall with white Plastinamel. The Plastinamel must be applied with a brush, but smoothes out readily after application. It will also go through a 'ruling' pen (as used in mechanical drawing), so that the trim color decorations can be drawn on the model with a ruler and French curves. Because of the beaded surface of the foam, masking tape does not work very well for trimming and therefore drawing the color scheme on and then filling in between the lines with a brush is the recommended procedure..."

Note this kit used the SIG (tapered) foam wing. For a plan showing how to construct a replacement wing in balsa see: Sig Foam Wing (oz16499) thanks to MarkWinstanley.
