Update 8/6/2024: Added article thanks to AndySnelson. This is chapter XV from the book "Models for Flying" by Rippon and Sparey, circa 1938.

Quote: "Chapter XV: The Premier Lion Monoplane.

In chapters 9 and 10 some notes are given on model petrol-engined aeroplanes. The Premier Lion high-wing monoplane, of which a description follows, presents a typical application of these notes in actual practice. This machine is powered by a 9 or 10 c.c. engine.

The machine under consideration is one of the most stable and consistent flyers that has been seen on our model-flying fields, and was the winner of the " Sir John Shelly Cup " for petrol-driven model aeroplanes. Since its advent the machine has made some hundreds of flights without mishap - a fact that is a sufficient guarantee that a replica built with reasonable care and faithfulness will well repay the builder.

Again, the reproduction of the drawings in figs. 167, 168 and 169, arc necessarily very small. Nevertheless, an idea may be gained of the general type and construction of the aeroplane.

The machine is of mixed construction - a judicious blending of hardwoods and balsa. Any 9 or 10 cc engine is suitable. The original was fitted with an 'Ohlsson' two-stroke petrol engine, and the only alteration necessary to the design, to accommodate any suitable engine, will be to the engine mounting and cowling.

Fuselage: The fuselage is built upon the longeron and plywood former system, and it is, therefore, advisable to cut all the formers from 1 mm plywood, to the required sizes, as the first step. Along all the outer edges of the formers, strips of 3/16 square section balsa are cemented, and should be left until thoroughly set before beginning further work.

All the longerons are of 3/16 in square section hardwood - birch is very suitable. Six longerons are used, and a start should be made by tying the two centre longerons together, with thread, at the rear ends. Next, glue the formers into their respective positions, and again leave until the cement is set.

The thread may now be undone, and the sternpost glued into position. When these joints are hard, glue and bind on the two bottom longerons to the sternpost, and proceed to cement them to the formers, using elastic bands to keep them in position until the cement is set... "

Many thanks to Brian for scan of the Aeromodeller 1946 advert, showing the model photo [also more pics 003].

Hi Mary, I have a photo for Outerzone of the Premier Lion [more pics 004]. I took it in 2003 at Middle Wallop. I remember talking to the builder for quite some time. Perhaps he will see it and post a pic of the finished model.

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.
