About this Plan

Spitfire XII. Radio control scale model WWII fighter, for .29 power and 3 function RC.

Quote: "This .29 powered version of the clipped-wing' Spitfire spans only 42-1/2 inches. It's for hand launching (no u/c), handles beautifully and really looks right in the air!

OVER the years, enough superlatives have been written about the Spitfire to sink the proverbial battleship, and I certainly don't intend to add my ha'pennyworth to them in this article; instead I will confine myself to a brief description of the origins of both the model and the full size.

The full size The Mk. XII came into being as a hasty counter measure to the then new and superb Fw190, these German fighters attacked low and fast over the South Coast (usually operating in pairs) and the RAF pilots soon found that even their Spitfires were out-matched, and their hard-won air supremacy was very seriously threatened. It was only the Spitfires' extremely tight turn that saved them from being massacred on several occasions. As the new Spitfire IX was not then coming off the production lines, it was obvious that something had to be done quickly. Vickers Supermarine took a basic Mk V airframe and married the new Rolls Royce Griffon engine to it. A larger pointed rudder and clipped wing tips completed the basic conversion, and this aircraft proved to be the answer to the current problems. Once again, the Spitfire met the enemy on equal terms.

As your esteemed Editor knows well by now, my pet 'hobby horse' is the small scale model, and I feel that this type of model is definitely a viable proposition for the experienced week-end flier. As the Spitfire had the reputation of being a bit 'hairy' when reproduced in model form, I felt that success with a small model of this famous aircraft would go a long way to proving my point.

Well, successful it certainly has been. It has now had many flights, and has survived an inverted pile-in from about 8ft up (pilot error). In flight, the model is a picture of realism and the glide in a power-off situation really has to be seen to be believed. One of these days I'm sure it's going to catch a thermal! An undercarriage has been omitted in the interests of realism, drag and, of course, our old enemy weight.

Being very clean, aerodynamically speaking, and lightly loaded, the model has plenty of power on only an Enya 29, and in fact has a fair turn of speed, but it can be slowed down considerably without any fear of the dreaded tip-stall. The prototype model uses very little ply in the construction, but despite this is strong where it matters. Only three servos are used (no rudder) to save weight..."

    ScaleType: This (oz9822) 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.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Supermarine_Spitfire
    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.

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.
