    ScaleType: This (oz15157) 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/Martinsyde_S.1
    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

I am a great admirer of Tom Hallmans skills but his plan is a little inaccurate. Those cabane struts should be vertical not slanted forward. I know this because I made the same error on my larger compressed air powered S.1 which was scaled from an inaccurate R/C plan by Peter Rake! Tom Berrymans plan gets it right and you need to know this stuff if entering scale comps.

And if the 3-view shown on the plan was the one used for the model, then it would be accurate. We all know that every 3-view is an accurate depiction of the actual aircraft, right. It would be nice to see the 3-view Mr. Berryman used for his model. I have only seen one drawing where the cabanes were clearly shown as vertical.

Well... I'm just gonna point out that in the photo in the Wikipedia link, presumably of an actual full size example, the struts do appear to be slanted forward (keep in mind the plane is sitting on the ground at, uh, what, some 20 degree angle, so actually they look nearly vertical upon initial look). So... do we believe Peter or the photo?
RC Yeager - 09/03/2024
Of course, Peter was referring to the "cabane" struts while I'm referring to the "interplane" struts. It wasn't until almost 5 hours later while doing something completely unrelated that I suddenly realized this and came back to Oz to check, and of course... So... never mind! :-)

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.
