About this Plan

Cessna AW. Jumbo scale model for rubber power.

Quote: "If you think Peanut Scale is popular, you should see what draws the biggest crowd when there's a combined Peanut and Jumbo contest! Peanuts are cute, but these big scalers are majestic! Jumbo Scale Cessna AW, by Jim Adams.

The Cessna AW Monoplane was the first cantilever wing, four place type manufactured and flown at the company's field in Wichita, Kansas. It was powered by a 200 hp Wright Whirlwind engine. The plane was also available powered by the Siemens or Anzani engines, as desired by the purchaser.

A close look at the plan shows the family resemblance to the famous pre-war Cessna Airmaster and today's Cessna 195. Obviously, the AW is the granddaddy of all of them. The Cessna Monoplane had a wing span of 40 feet, 6-1/2 inches and length of 23 feet, 8-1/2 inches. The wing was constructed of spruce and plywood, while the fuselage, landing gear and tail group were made of steel tubing. The entire airplane was fabric covered. Outstanding features of the plane included its simplicity and distinctive appearance due to the lack of struts.

Construction of the model is very conventional and requires very little explanation. The most important thing to remember in building a Jumbo rubber scale model is to keep the weight to a minimum. This is true with all scale models, but must be particularly emphasized on the large ones. Extra weight will penalize your model during the climb by forcing you to add more rubber - which in turn adds more weight.

The 3/32 sheet stripped ribs (a la indoor style) are not absolutely necessary. If you should desire to use sheet ribs, use 1/16 light sheet balsa and substitute 3/32 square spars on the top and bottom of the wing in place of the sheet spars called out on the plan. The strip ribs are trimmed to the length shown on the plan by cutting excess length from the rear end of the ribs. Patterns are given, one for the ribs between the center and the rib half way to the tip and the other for the ribs from the mid-point on each wing panel to the tip.

Wing construction is started by pinning the leading and trailing edges down over the plan, and adding the 3/32 square lower ribs (Note: These are located at every other rib location.) Add the spars and then trim and cement the previously stripped upper surface wing ribs into place.

The recommended tail construction is laminated per instructions in Model Builder issues. The material is 1/32 x 1/16 inch basswood strips. Paper surfaces should be water shrunk after covering and given two light coats of clear dope. If you desire color, spray on a very light mixture of flat train paint and clear dope or clear lacquer. Mix approximately 50-50. Be careful here, and use pigmented finishes sparingly; this is where the weight can build up.

A technique that l have used for several years on tissue, silk span, and silk, either wet or dry, is to apply two coats of full strength dope to all framework where you want the covering to adhere, let it dry. Sand lightly, and then smooth on covering, using your dope brush to apply thinner to the paper. The thinner activates the dope under the covering instantly and dries very rapidly. Any blushing that occurs will be removed by the first coat of dope. If you get a wrinkle you can lift the paper by re-wetting the area with thinner..."

    ScaleType: This (oz13670) 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/Cessna_Model_A
    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.
