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..."

Good morning Mary. Some photos attached of Ladybird from your plan oz2132 and a Belair parts set [model pic, plus morepics 006,007]. An easy build with the parts set, I think it looks nice and flys great as well. Thanks for your hard work on our behalf. Very best regards :)

Notes

* 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.

Scaling

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.
