Spitfire - Radio control semi-scale model, for .40 power. Uses either foam or balsa wings.
Quote: - "If you've always wanted to fly a model of the Spiifire, and have been put off by all those tales of woe about terrifying vices, such as tip-stalls on take-off, etc - don't believe it; it ain't necessarily so! Here's one (though not 100% true to scale, more a sort of 'nearly-scale', I like to call it) that has quite good manners. A word or two here about the history of the prototype, might be of interest. The idea was first conceived when my club, The Guernsey Model Club became involved in preparing for a special Battle of Britain model flying display. I elected to put something together and was told: 'Don't worry - as long as it looks about right at 150ft, and you can keep it in the air for a couple of minutes - that'll do!' Well. I got a bit carried away and ended up with much more than that. I now have a model which is great fun to fly and has been used as a general sport model ever since the display.
The model is for motors of around the popular and economical .40 size. Mine flies well on an aging ST.46 well past its peak, so a good .40 will be more than adequate. It uses either a polystyrene foam wing with balsa leading and trailing edges, or conventional built up wing. We have to cheat a little - sorry, a lot!! - in order to reproduce that elliptical planform. The fuselage makes use of balsa-covered foam sections, which are light and make for quick, easy building. At this point I refer you to the excellent article in RCM&E April 1974, by Derek Hardman and Squire Kay which contains a lot of very useful information on this subject.
This design is of no particular Mark of Spitfire, the idea being that you can 'dress it up' to represent any one of the dozens of versions that were built. Also, no attempt has been made to satisfy the purists, who must have true scale outline at all costs! Importance has been placed on ease of flying, coupled with quick and easy construction, in an attempt to offer the average club flier a model which, in the air particularly, will be instantly identified by almost anyone as a replica of the greatest fighting aircraft ever built."

Did we get something wrong with this plan? That happens sometimes. Help us make a correction
* 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.
