About this Plan

Ryan PT-20. Scale rubber model. September 1944 Aeromodeller.

Update 30/12/2012: Thanks to BryanLea for mailing in some fine photos of his completed model and a cautionary note to check carefully the incorrectly drawn wing spar before commencing a build from this plan.


Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

    ScaleType: This (oz1703) 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.

Attached are some photos of my Ryan PT 20 built (circa 2005) from the Aeromodeller plan of 1944 by Edgerton [003, 004]. There is unfortunately a problem with the plan in that the spar is drawn wrongly. The following is from an article that I wrote at the time: "The wing is monospar construction with 1/16in reed outline for the wing tips. I substituted 1/16in aluminium tubing for the reed, this modification applied to the tail plane as well. I made up the spar to the full span in one piece with dihedral keepers which I made from thin ply instead of 1/16in balsa as drawn in the magazine. It was only when I had a complete wing and offered it up to the fuselage that I realised that something was wrong. The flat section of the wing, which sits underneath the fuselage, was too long compared with the width of the fuselage. Oh bother! Nothing for it but to start again. I suppose with hindsight I could have probably just sawn it in half losing the offending bit and glued it together with a bit of ply reinforcement."

* 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.
