Free flight, PAA-Load, a dream . Twenty flights, including 14 at the Nationals, before this article was written, proved the airplane a successful, stable performer. ► The Mooney Mite is a low wing single place light- plane powered by either a Lycoming or a Continental 65 hp engine. It has tricycle retractable landing gear and a sliding hatch which, coupled with its trim looks and modern design, make it resemble a little fighter, lhe airplane flies as well as it looks. So when the author of this article found out that Dallas Sherman of PAA-Load fame had a Mooney Mite which he was using as a retriever at large con tests, a PAA-Load free Might flying scale model was inspired. This inspiration, it must be admitted, was helped along by a letter from Mr. Sherman suggesting that lh e Mite be built. 'lhe original has a very gaudy color scheme which makes the model even more fun on the field. The model Despite sturdy construction, the little Mite weighs only 16 oz. for looks like quite a challenge in view of the widespread free flight or 21 oz. with payload. Trim, balance are same for both. prejudice against low wing models in general but with only two deviations from exact scale, it flew right off the board. The horizontal tail was increased slightly in size and the dihedral was raised to supply the added stability needed in the model. The model in the article has been flown 20 times, including 14 flights at the 1955 Nationals. It will fly with or without the payload with out any trim changes. Weight, empty, is 16 oz. and, with the payload, 21 oz. Construction on the model follows full size practice almost exactly, substituting silk for fabric and sheet balsa for plywood. The fuselage is planked where the real ship is planked and the rib-spacing is to scale. All surfaces were made separately and hinged with soft wire for adjustments which, as it turned out, were not needed. The flaps on the model were in the 10° down position to give the effect of an undercambered wing. Scale wing sections and scale washout (wing twist) were used to prevent tip stall which might otherwise be present in a tapered wing. If the model looks overly complicated, it should be pointed out that making the surface integral with their forward counterparts will in no way hurt the model’s Father of the PAA-Load event, Dallas Sherman, had idea for the pay- load model of personal Mite. Walt Mooney also is a real Mite pilot. flying ability and should result in a slight weight saving. MODEL AIRPLANE NEWS · January. 1956 9 Simply use tapered trailing edge stock on the wing and run the ribs all the way back. Do likewise with the vertical and horizontal tail. Then the surfaces can be marked on in black paint. For scale contest flying, however, the separate surfaces are worth their produc tion trouble in scale points at the judging. The vertical and horizontal tails are pretty conven tional and fairly simple, so build them first. The stabi lizer (I fixed part of the horizontal tail) shows in the factory three-view to be flat on top in the front view with the bottom surface tapering up. Therefore, plank one side with the leading edge while it is still on the ί work board. Then the slide against the board becomes the top of the stabilizer, since it will be fiat.

While this is drying, bend the main landing gear from 1/16 dia music wire. Remember to slip the piece of aluminum tubing over the wire before bend ing it. When the one wing is dry, block up the tip for the correct dihedral and, keeping the aft part of No. 2 rib on the board, install two No. 1 ribs and the other No. 2 rib.

When dry, the wing skeleton can be raised from the board, the LE trimmed and the LE sheeting added. Separate pieces must be used between the No. 2 ribs and between the No. 2 and 4 ribs because of the change of taper at these points. Now add the second piece of the aft spar, which is JS jg x triangular in cross-section. Build up the ailerons and carve the flaps from 3/16 sheet balsa. Before sheeting the bottom of the wing LE, install the main landing gear.

Note open cabin door. By FLOYD GUYTON ► The Waco Cabin, as it was commonly known, was built between 1931 and 1940. It boasted greater stamina, speed and desirable performance than any other air plane in its class. With its compact size, easy handling From the Pacific Northwest comes this Half- and pleasing appearance, it made an ideal luxury, A scale model, a grand flier, contest winner. family or businessman’s air vehicle. Not exactly cinch to build, but worth it. The model, winner of the ’54 Jim Walker Northwest Championship, drawing top points for scale, reflects all the ruggcdncss and stability of the original. Appear ance is enhanced by clean fairings and smooth lines. Very few changes were made from true scale. The dihedral was increased from 2/2 to 4'' and the stabilizer area slightly increased. The widespread landing gear and large rudder facilitate unassisted take-off. This model is not as difficult to build as it may ap pear. The sequence of construction is of prime im portance. Tail surfaces are self-explanatory, except that the stabilizer spar and front outline will be duplicated by extending on through to make the other side. Wings are built up in the usual manner. Dihedral may be spliced into wings directly over wing views of draw ing. Leading edge top sheeting should follow splicing. Then build up fuselage square in usual way, noting entrance door on left-hand side only; reserve the door construction for later. If you wish to upholster the in terior, this is the time to do it. Unassisted take-offs just come naturally for a real looker like this. That Area from back of entrance door from B5 to T6 color scheme, incidentally, is Waco maroon with black trimming. station between baggage compartment and rear win dow should be covered with Silkspan to separate bag gage compartment from cabin. Interior was painted one coat of light gray dope, floor is 1/32 sheet balsa, bag gage compartment floor was corrugated and may be simulated from corrugated paper found in packaged cookies and similar articles. Build up seats and controls, paint gray and cement into positions. Add stringers only to sides of fuselage. Now build out frame around entrance door of 1/8 x 1/16 stick, inside opening, to make sure of exact fit. Entrance door is hinged with three layers of Silkspan. Install formers T1 and T2; also, 1/32 sheet areas from T1 to T2 around sides to lower longeron as shown in shaded areas. Cut out window frames of 1/32 sheet, check for fit, treat both sides with Silkspan, paint gray on inside and black on outside, cement celluloid win dows into place and install. Windows should be cov ered with masking tape as protection against dope and Unusual feature of Waco Cabin was the interplane strut system which, on model, adds crack-υρ resistant rigidity. Glow plug juts through cowl. cement. Sides of fuselage, wings and tail surfaces may be covered at this time.

If there is a bend at an inside comer, a large hole is necessary to avoid cracking. It is a good idea to use a pair of gloves when cutting the pieces out for a cut from aluminum can be serious. When you have the pieces cut out, take a fine file and round off all edges and remove all burrs. If there are spots where a sharp curve prevents your making a smooth cut, a half-round file will help greatly. When you have the pieces ready to start forming, begin with the vertical fin or rudder (as the easiest piece to form), holding with both hands, and mb the inside surface over the edge of your bench until you have a slight curve in the entire piece.
