About this Plan

Supermarine Sparrow. Radio control scale parasol model, for .020 power.

Quote: ".In 1926 the Supermarine Sparrow II was rebuilt from the unsuccessful Sparrow I biplane. Sparrow II was a two-place parasol monoplane powered by a 32 hp Bristol Cherub III engine. The wing span was 24 feet, and the maximum speed was a scant 65 mph. The Sparrow could be called, by many, a homely airplane. As often is the case, these homely airplanes have a great deal of character.

Checking it over as a possible model, it has all of the right proportions to make it a good stable flyer and, due to the basic squareness, is a joy to build. The model is built to an odd-ball scale of 0.94in = 1ft. This is the result of finding the right size vintage wheels, then scaling the plan to the wheels! Another reason for the odd size is that I wanted to be able to incorporate the Ace foam wing.

The construction of the model is very easy and should give no one any trouble whatsoever. The only thing to keep in mind is to make certain that you choose your materials carefully so that the weight buildup is not too high.

I always start with the fuselage - for once this is completed, it spurs me on to complete the model. The sides are cut from medium-weight stock and the front doublers from hard balsa. After cutting out the two sides, mark the location of ali bulkheads and servo runners, plus drill the holes for the aluminum strut tube. The bulkheads that carry the tubes for the cabanes are cut from 1/16 plywood and the firewall from 1/8 ply. Cabane tubes? What are they? If you take a good look at the pin you will see just exactly how these are incorporated. Instead of the usual way of bending the cabanes and permanently mounting them onto the fuselage during construction, I prefer to bend the bottom..."

* 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.
