About this Plan

Ryan ST. Free flight scale model for rubber power. Wingspan 30 in.

Quote: "General Information: All of the parts on the plan are identified by a number or a letter. Parts identified by a number are laser cut parts. Parts identified by a letter are stripwood pieces that you cut and fit on assembly. The slight discoloration of the edges of the laser cut parts may be removed by lightly sanding them with 400 grit sandpaper.

Your kit contains the following parts. Please check your kit for any missing or damaged parts before starting construction...

Beginners Note: These instructions were written assuming that the builder has previous building experience. If this is your first model then we recommend that you purchase a copy of the following book: Rubber Powered Model Airplanes, by Don Ross. This excellent book covers basic building and flying procedures and provides valuable information about all aspects of building and flying rubber powered model airplanes.

Building the Fuselage:
1. Pin the plan to the building board and cover it with wax paper.
2. Pin the fuselage keel pieces #1 through #5 into position on the plan.
3.Position #6 on the front of #1 and #5. The top and bottom of the formers may be determined by the location of the slot for the master stringers #17 and #18. Use a small square to hold up #6 at a 90 degree angle to the building board. Glue #6 into position.
4. Carefully glue formers #7 through #16 into position on the fuselage keel making sure that they are 90 degrees to the building board.
5. Assemble the master stringer over the top view on the plan using #17 and #18. When the glue is dry, position the master stringer onto the fuselage assembly and make sure that it is pressed completely. Now glue the master stringer into position.
6. Glue former #19 into position.
7. Glue the fuselage stringers ("A") into position. Splice two pieces together if required to get the correct length. The top two stringers stop at the front and rear of the cockpit areas.
8. Remove the fuselage from the plan. Add the formers to the oppositie side of the keel and glue the master stringer into position. Now glue the remaining stringers into position.
9. Wet the outside only of one #20. Allow it to sit for several minutes and then fit to the fuselage. Glue it into place when you are satisfied with the fit. Now repeat installing the other #20 to the opposite side of the fuselage..."

    ScaleType: This (oz15383) 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/Ryan_ST
    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.
