About this Plan

Sopwith Triplane. Free flight scale model WWI fighter, for rubber power. Scale is 1/8.

Uploaded to the HPA site (see Datafile) by Greg Thomas, the designer.

Quote: "This is a 1/8 exact scale rubber power free-flight model of the Sopwith Triplane. All full scale documentation in developing the model came from Jim Kiger of Replicraft. Every detail that could be replicated at this scale is shown. It was intended to be a 1/8 scale kit but will not be manufactured due to the projected high costs of doing so. The entire airplane has been 3D modeled to guarantee every part shown will fit precisely as indicated on the drawing set. Greg Thomas"

Quote: "Although this document is a copyrighted document and may not be used to manufacture in any form, a production kit of this design as shown here, it is given freely to the modeling public via 'Hip Pocket Aeronatics' for personal use in creating the model portrayed here. ThomasDesigns retains and reserves the production rights to manufacture the model as shown on these documents. Signed, Gregory J Thomas 16 Apr 14, for Thomas Designs."

    ScaleType: This (oz13228) 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
    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.
