About this Plan

Karin. 45in span contest winning rubber FF model from Model Aircraft, November 1962.

Quote: "Karin, by R Linton. A contest winning rubber model with eye-catching lines. Build it with the help of these detailed instructions.

Fuselage. This is quite straightforward. Selecting hard, straight-grained stock, pin the two main longerons on to the side-view of the plan, placing the pins on either side of the strip and not through it. The lower longeron will have to be spliced near the tail to make up the length. Cut four nose pieces from 1/8 in hard sheet, making sure that they are all identical and add one to the longerons and also the tailpiece and motor mount. Now simply fill in the Warren spacers.

Sandpaper the upper surface when it is dry, cover with greaseproof paper and then build the second half over it. Separate the two halves and add the ply facing to the motor mounts. Prepare two of the formers 'A' and cement them to one fuselage side, checking their alignment with a set-square. When dry, cement the other half on to the formers, checking the alignment of the nose sections as before. Cement the two remaining nose pieces on to one section of the nose and, once they have dried thoroughly, draw the whole nose together and cement well, binding with cotton thread. Add the spacers.

Make up the pylon sides as for the fuselage and assemble them over the top view of the fuselage with four horizontal spacers. The forward fairing comprises two semi-circles of 1/32 in, sheet and a wall in. deep the rear fairing is a simple triangular box. The pylon is cemented onto the fuselage and the fairings then added.

Form the outline of the fin from 3/16 x 1/16 in strip and the ribs as detailed on the plan. It will be seen that the ribs are divided, one half being 1/16 in deeper than the other and slotted at the ends. These deeper sections are pinned on to the outline on either side of the spar..."
