Flyabout (oz4758)

About this Plan

Flyabout. Free flight cabin model for 1/2A power.

Quote: "Designed expressly for beginners, this ship is attractive and extra sturdy.

The Flyabout is a realistic sport model for engines of .02 to .074 displacement. It will fly but not take off with the .02 and is over powered with the .074 so either the K & B Torp Jr at .035 or the O.K. Cub .049 are its proper power plants. The ship shown in plans and pictures performs well on the .035.

About the only features out of the ordinary are the three-wheel gear, permitting automatic take-offs, and the sparless, tapered wing. The fuselage is all sheet, paper-covered, as are the tail surfaces. The Flyabout is easily made in two days and a fast working expert can have it ready to fly in a day if he bears down.

CONSTRUCTION: By joining the sheets of plans alone their long edges as keyed a full site plan results for the fuselage, rudder, and one-half the stabilizer; when finished with these portions, sheet two and three can be rejoined to provide one half of the full-size wing drawing, which is quite easily reproduced right hand for the other half panel.

The fuselage aides and formers are 1/16 sheet balsa, the sides being butt jointed for width on the forward half of the fuselage. The main formers beneath the wing are a standard 2 in wide for simplicity. If construction is to be easy, several minor points need consideration before making with the razor blade. Note that the profile of the fuselage on the plan includes the top and bottom sheet covering, which means that 1/16 should be removed from the absolute profile along the entire bottom, and on the top from the wing back. The 3/32 thick cabin roof fits within the sides; the bottom sheeting, at the point of difficult bend on the bottom of the fuselage, has its grain running cross-ships. From the landing gear back, the bottom sheeting has fore and aft grain.

The easiest procedure for an accurate fuselage is to place the 3/32 sq side pieces in the notches on formers 2 and 4, then cut out and glue in place the cabin roof. When this dries add the two sides, but do not join them at the rear.

Now follow up with formers 1 and 3 and only then bend the sides until they meet at the tail with a natural curve. Formers are not given for the section of the fuselage behind the wing because their widths should match the station widths of your fuselage. Since the formers are rectangles it is a simple matter to measure depth and width from your ship. Note that former 6 has its grain across-ships; if any formers tend to buckle, reinforce them with a piece of 1/16 sq across the grain.

Before adding top and bottom, construct the landing gear sandwich of three pieces of 1/16 sheet (see plan detail) and, having bent the main landing gear to shape, install the sandwich in the fuselage (check side view), filling in between it and former 3 with 1/16 sheet..."
