About this Plan

Wee Waco (Wee WaCO2). Free flight all-sheet model for CO2 power, by Ken Willard. September 1948 MAN.

Quote: "An accurate replica of a famous biplane, this model is a fine flier with its CO2 power. Wee Waco, by Ken Willard.

DO YOU like flying scale models? Do you like biplanes because of their realistic appearance in flight? Have you hesitated to build a free flight, flying scale, gas-powered biplane because you feared the results of a crash during adjustment, or couldn't find a suitable large open area for flying the model?

Well, here's the answer to all your problems - Wee Waco. If carefully constructed and properly adjusted, Wee Waco is one of the best scale models you will ever fly. It is ideal for those quiet summer days, and it will handle a light wind too. Best of all, you can make it in a couple of evenings.

The appearance of the CO2 engine has been accompanied by a marked increase in free flight activity because it eliminates the necessity for a large open field. As an oldtime enthusiast for free flight, I was intrigued by the possibilities of CO2, and when the Campus A-100 was introduced any open lot became a flying field. Also, the local park board, dead set against the noisy power models, hasn't said a word against these tiny replicas of the bigger gas jobs. You will find that the only problems associated with flying the small CO2 free flight models are those connected with the adjustment - and if you've been a controliner all this time you've got some mighty interesting days ahead when you start learning the secrets of free flight adjustment. But these little CO2 jobs will take a terrific beating because they are so light, and repair is a simple job even after a power dive crackup, since the sheet balsa construction allows it to be glued back together right at the break.

Let's get on with the construction of Wee Waco so we can take it over to the corner lot and do a little flying - or take it over to the controline circle and watch the boys stare in amazement as this little job flies in left hand circles, righting itself automatically when disturbed by the breeze. Be sure you have it adjusted, though, to avoid the horse-laugh. We'll talk about adjustment later.

First, go to your hobby shop and select your wood. You won't need much, but it will have to be of the very light-weight variety. As you know, some balsa is three or four times heavier than other stock. Avoid such a grade. Get the very lightest grade except for two pieces - the engine mount and the tank bed which should be of medium grade (not heavy!) balsa. Study the plans for a few minutes and look at the photos. After you have the general idea pretty well in mind, make templates for the fuselage sides, formers, wings and tail surfaces out of stiff paper by tracing directly from the full size plans. Be sure to cut the fuselage side template to fit the outside edge of the heavy outline. Now you are ready to make the fuselage.

1. Cut fuselage sides from 1/32 sheet balsa.
2. Cut fuselage formers from 1/32 sheet. Cut two of each, grain upright on one and sideways on the other, then glue together crossgrained.
3. Glue 1/16 square brace on inside of fuselage sides as shown on plan..."

    ScaleType: This (oz2380) 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.

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

* 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.
