Curtiss Goshawk (oz15076)

About this Plan

Curtiss Goshawk. Free flight scale model fighter biplane, for rubber power.

Quote: "Building the Curtiss Goshawk. By Paul W Lindberg, Professional model designer.

THIS model of the Goshawk has been accurately designed to scale and our laboratory tests show excellent performance with this biplane. Flights between 400 and 500 feet are easily obtained, and let us say right here that it takes to the air like the actual ship itself. After the rubber turns are exhausted you will be thrilled at the sight of your model gracefully gliding into the field for a three point landing.

There need be no fear of washing out the 'landing gear as our laboratory has designed an ingenious type of shock-absorber fitted into the landing gear struts. This, with adjustable control surfaces mounted on aluminum hinges, improves construction and the explicit detailed plans will be of the utmost help to the model builder.

In building the model of the Curtiss Goshawk Fighter, all dimensions can be quickly and accurately determined by placing a ruler on the part to be measured as the plan is printed full size. If you wish a larger model, multiply this measurement by the amount of increase. The color scheme can be obtained from the cover of the February issue of Poplar Aviation.

CONSTRUCTION OF FUSELAGE: The fuselage sides are built from inch square square balsa. The longerons, ver-ticals, diagonal braces, etc., are held in place until securely cemented by inserting straight pins on either side of strips wherever needed. After the two sides are completed, they are pinned to the top of the plan in such a manner that the top longerons face down and so that the sides form right angles with the surface of the plan. The cross-members are now cemented in their proper locations. Cut formers from 1/32 inch sheet balsa and cement in their respective positions as shown on the plan.

All 1/8 inch stock is used at front and rear of fuselage, made oval as shown on plan in order that 1/32 x 1/16 inch stringers may be cemented to them, and in turn carried over remaining formers to rear of fuselage. Please note that the stringers are cemented to outer edges of formers. This is necessary in order to obtain a smooth covering job, and eliminates all projecting formers or bulk heads. Formers 5 and 6 receive stiff paper for cockpit cowling.

The former between formers 9 and 10 is cut from a heavier block of balsa. Pay very close attention to the manner in which it is formed, as this forms an air passage similar to those on the large ship. After the two front side cowls have been applied to either side of fuselage, use stiff paper or balsa veneer for the side cowls.

DUMMY MOTOR: The motor is built up entirely from balsa and sheets of paper. The cylinders are built first using the sheets of paper cut into disks, etc., to represent the fins. The layers in between these are made of sheet balsa 1/32 inch in thickness. These are cut smaller so as to make the cylinder more realistic.

The crankcase should be made from layers of 1/8 stock cemented together and shaped as shown on the plan. A solid block of balsa may be shaped up equally as well. After the cylinders and crankcase have been completed, cement the nine cylinders in their proper locations on the crankcase..."

Quote: "Dear Steve and Mary, Here is a plan by Mr. Paul Lindberg for the Curtiss Goshawk. The plan appeared in the March 1934 issue of Popular Aviation magazine. It looks as though it was inspired by the subject on the cover of the issue for the previous month and its accompanying article; all enclosed.

I have not stitched it together yet [fixed now] because there is a slight gap in the printed plans with some details which need to be filled in, but it should not present any problem, and all the published data is there. It would undoubtedly make an attractive model. Kind regards,"
