About this Plan

Tipsy. Rubber scale model. From Aeromodeller Jan 1942.

Quote: "Construction: Fuselage: First of all, obtain a block of soft balsa, 2 in by 11 in by 2-5/8 in, and carve carefully to shape. When this is clone, split the block down the centre-line and hollow out to wall thicknesses shown, not forgetting to leave a 1/4 in hole for nose-button.

The rest of the fuselage is made on the stringer principle. Pin master stringers on the drawing and cement half-formers on to these. When dry, remove from plan and complete the fuselage by adding opposite half-formers, the two side stringers and the tail-blocks. Cover the entire fuselage except the turtle-back with 1/64 balsa; add bamboo stringers and cover with tissue. Also cut a portion of the balsa covering away for insertion of rubber. Pierce holes in fuselage and cement drinking straws firmly into position.

Wings: Place spars in position on plan, also the trailing edges. Slot ribs and cement on to the spars. Rib C is cut from hard 1/4 in balsa, to which the landing gears are fitted. Cement wing tips in position and cut slots for and fit leading edges. Cover wing to dotted lines with 1/64 sheet balsa and place 1/16 sheet stiffening in position on underside of wings. Locate wing dowels from straws in fuselage and cement in position. Cover rest of wing with tissue.

Empennage: The construction of the tail and elevator is very similar to that of the wings. Cut all ribs to streamline section and cement spars in position; attach movable parts by means of aluminium hinges. Stabiliser rib A-A is made of 1/4 by 1/16 balsa, and tips are of 1/16 sheet.

Undercarriage: Cut two shapes of 1/4 in balsa and four of 1/8 balsa. Cement one piece of 1/8 each side of 1/4 sheet after space to take wheel cut out. Carve to streamline section and fit 3/4 in balsa balloon wheel. Strut is carved to section Y-Y and cemented to spat. Force a 1/16 diameter bamboo peg into the strut, and attach landing gear to rib C.

Covering and General Finish: Sand fuselage with extremely fine 'garnet' paper and give one coat of clear and two coats of coloured dope. Cover turtle-back with tissue paper and add the dummy engine, which may be made by winding thick thread round balsa cylinders and adding valve rods and spark plug leads to make a realistic job.

Flying: Fit a 5 in 'wind shovel' type propeller and two or three 12 in loops of 1/8 by 1/30 in rubber. Add very small weights to nose or tail until correct trim is obtained."

    ScaleType: This (oz12033) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.

    ScaleType is formed from the last part of the Wikipedia page address, which here is
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
