About this Plan

Navion. Scale model for control line.

Direct submission to Outerzone.

Quote: "Steve, Attached is a plan page for the Ryan Navion in control-line, from a 1960's edition of Mechanix Illustrated (sorry, I don't know the year or month of the issue). I've got the original page, which was in horrible condition due to age. It took some time to salvage it and get it strong enough to scan, but the results were worth the time. I'm currently building this plane modified for RC. As with many of these plans, the dimensions of the parts can be a little off, but that is to be expected. This is a complete plan, all formers and components are shown. Thanks,"

Update 22/11/2021: Added article, thanks to Pit.

Quote: "An accurate easy-to-build-and-fly scale gas model of North Ameri-can Aviation's entry into the lightplane field. Span is 36 inches. Navion, by Paul Plecan.

SLANTED at the higher-priced end of the sportplane bracket, the North American Navion promises to be one of the outstanding ships in the lightplane field. Combining a luxurious, roomy cockpit with high performance at moderate cost, the Navion stands out like a sore thumb in comparison with other models in its price class. Looking much like the P-51 Mustang, as North American's first entry into the private flying field, the Navion should prove as popular to the public as its fighting brother was with thousands of Allied fighter pilots during the war.

Possessing fine proportions for a control-line model, the Navion makes a snappy looking job. The clean, yet roomy cowling allows the installation of large motors, although for sport flying we recommend engines in the Bantam or Ohlsson 23 class. And you'll find the tricycle landing gear is also easy on prop breakage. Full-sized plans are a requisite, so unless you are unusually adept at enlarging magazine drawings, it will pay for you to send to the MI Reader Blueprint Service for the full-sized drawings.

Fuselage Construction: Commence building the fuselage by cutting out the backbone, F-13, 14, 15 and 16 from soft 1/4 in sheet. Since these are merely 'keels' and are not intended to absorb shocks and strain like the planking, there is no need of adding unnecessary weight by using hard balsa. With the exception of the wing spars, use soft or medium-soft balsa for everything, as a very heavy model will respond poorly to the controls. Cut out two of each former shown on the plans and assemble the half of the fuselage directly over the plans.

After cementing a few planking strips to the formers to help keep the shape, the fuselage half can be removed from the workbench and the other half added. If an engine other than a Bantam is used, the positioning of the motor bearers will have to be changed in order to keep the thrust line in the right place. While planking the fuselage, remember that a removable nose portion will allow engine adjustments and filling of the gas tank, so be sure to cut away the upper portion of the nose cowl..."

    ScaleType: This (oz6283) 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/Ryan_Navion
    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.
