About this Plan

The Champ. Free flight profile scale model. An all-sheet design.

Quote: "The Champ, by Harry Williamson.

If you haven't got around to that super-duper scale job, why not let off steam with this well performing sport model. For .039's - .049's, it's robust, good looker. Swell subject for first gassie.

How many times have you said to yourself one of these days I'm gonna build me a scale free-flight job, only to find that you never quite got around to it? If you're like the rest of us, its probably happened numerous times. There's always a good reason why it never comes to pass but the root of the difficulty seems to be insufficient time or a reluctance to put forth the effort required to produce a good-looking scale job. Then, too, there is always that nagging tear that the prodigious labors put into the true-scale model may be instantly dissipated in a crack-up.

Well, maybe we have the answer to an embryo scale free flight modeler's dream! The Aeronca Champion model described here provides all the kicks of scale flight, with a big reduction in the labor required and, in addition, it is strong enough to take the punishment normally meted out during flight tests by the less experienced builder.

A conscious effort was made to keep this model as close to scale as possible in outlines, except for the changes required to provide stability and complete simplicity. Any Half-A engine between .039 and .049 displacement will start you in business. The ship ready to fly weighs about 10 oz with a wingspan of 34 in and an area of approximately 170 sq in.

Trace the outline of the fuselage on a piece of stiff cardboard and, using this as a template, trace the outline on 3/8 sheet balsa. Carefully cut around the outline (don't forget the slot 3/32 wide for the stab) and edge-cement the sheets together as indicated on the plans.

Mark off the location of the landing gear on both sides of the fuselage and carefully gouge out the re4cesses to a depth indicated with the point of a razor blade or knife. Trace the outline of the firewall on a piece of 1/8 plywood and cut to shape..."

    ScaleType: This (oz13479) 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/Aeronca_Champion
    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.
