Cumulus 48 (oz4791)
About this Plan
Shereshaw Cumulus 48. Radio control sport model for electric power.
This is a modern re-drawn plan.
Published in 1937, the original Ben Shereshaw Cumulus (oz5363) free flight design was first seen in Flying Aces. This here is a later redrawing for radio control and electric.
Quote: "I've spent the last couple of days with the magazine plan and article on the Shereshaw Cumulus. With the copying over the years and who knows what else, plus the necessary small scale, simply blowing it up wouldn't do. So I set about drawing something up that I could cut out the parts and be reasonably sure that they would fit. I fully expect a surprise or two, but there shouldn't be anything major.
I drew this at 48 in wingspan because that's what I intend to build, but the original was 96 in. I also made the changes needed to make it electric. It's an easy thing to double the size if you need to.
There are also things like the dihedral brace and spar bracing that is not drawn here. Anyone wanting to build one (with this plan or another) should absolutely read the magazine article. There are a lot of things explained there that are not obvious on the plan."
Supplementary file notes
Additional version of the plan in PDFvector format. Note the scaling is wrong on this one. Quote: "One thing, though, in the conversion from cad to pdf, wingspan went from 48in to close to 52in. If there is someone here who knows how to fix this and has the time to do it, then please do."
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

* 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.
