About this Plan

Stinson O-49 (Stinson L-1 Vigilant). Scale model for rubber power.

Quote: "Model builders will recognize the Stinson 0-49 as an excellent subject for a flying scale contest model. In appearance it is attractive yet not difficult to build. Best of all, the aerodynamic proportions are near perfect; our test model was built to scale and it was unnecessary to even increase the wing's dihedral or enlarge the proportions of the tail surfaces to obtain long, stable flights. The relatively long fuselage permits use of a powerful motor of considerable length, thus increasing the length of power flights. To make possible use of a propeller of sufficient size the landing gear is shown in the extended or flight position. In addition to its excellent flight qualities, the Stinson offers a wealth of detail to be reproduced in the radial motor, cabin windows, etc., for those who seek maximum scale points in flying scale contests..."

    ScaleType: This (oz8559) 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/Stinson_L-1_Vigilant
    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.

User comments

Enclosed are a couple of pictures of Earl Stahl's Stinson O-49 [main pic, 005]. The plans were doubled sized to 64" wingspan. I converted it to 3 channel RC. Powered by a Magnum .15. I enjoy your website as it inspires me to keep building. Thank you!

Would you kindly give some hints about how you 've built the undercarriage? You say you doubled the size of the model. That means a much heavier model sits on those legs and its supportive struts. What material did you use for the u/c? What strength of wire? Did you solder those wires? Exists maybe a drawing of your solution to this all?
Would be greatful for your information.
Thank you.

Robert, That was the weakest part. I soldered the wire landing gear just like the example shown on the plans. Don't remember what gauge piano wire I used. The struts were reinforced with plywood and shaped with balsa, then covered with silkspan. The under carriage was attached to plywood bulkheads. I had to land gently, or bend it back to its proper shape. I hope this helps!

Thanks, Dan, very helpful your information.
Venerable Kermit Weeks has not only his impressions of the Storch on YouTube, he flew also one of the last L-1 survivers and he confronts us with interesting facts indeed.
Look how low the Stinson sits on its u/c legs even when without pilot/passenger. It's the same problem as with the Storch modelbuilders have to
compromise how they construct the L-1 u/c.

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.
