About this Plan

Ladybird. Free flight rubber biplane sports model. April 1948 Aeromodeller.

Quote: "IN these days when model design seems sometimes to be stagnating, it is always refreshing to sample any model that is a little out of the ordinary run of things, and it is especially satisfying when such a model is capable of a performance to gladden the most exacting of sport fliers. As readers will see from our cover painting this month and the accompanying photographs, the designer has delivered a most elegant little free-lance biplane which is just the right model to keep handy for flying at any time when the weather offers a useful spot of fine.

Construction is very strong but straightforward, and the machine is rugged enough to stand up to all-weather flying while being easy enough for the less experienced to build and fliy. Altogether the model can be thoroughly recommended to all who appreciate a different kind of design with a pleasingly orthodox performance.

Fuselage. This is of the slabsider type, and caw and accuracy should be taken during assembly to ensure correct alignment of the wings and tail surfaces, Build two sides on the drawing in the usual way, then cement in bulkheads 1 and 2, nose formers, and finally the top and bottom spacers.

Wings and Tail Unit. Build top and bottom wings in one piece, and incorporate dihedral by cracking through leading edge and trailing edge spars where shown, inserting the reinforcing pieces of 1/8 in sheet at the main spar joints. Construction of the tail unit is straightforward but a medium or even soft grade of balsa should be used to reduce weight, Cement the twin fins securely to the tailplane end ribs, checking for alignment.

Airscrew. A twelve-inch diameter airscrew was used on the original. This may be purchased or carved by the builder as desired. Apply several coats of clear dope sanding lightly between each.

Flying. First check model and C.G. position. Obtain right-hand circle flights by adjusting side-thrust and amount of rudder..."
