About this Plan

110% Viking. RC assisted old-timer model.

Quote: "The Cleveland Viking kit was advertised in 1940 as 'a sporty looking good flying model for the new small motors'. The engine reference was to the then new Ohlsson & Rice .23 and the Brat.

For many years the Viking has been lurking around in my sub-concious as a subject for an .020 replica project. A few months ago I hauled off and resurrected my old plans and scaled them into a delightful little 36in span fun type model. The flat sided fuselage and polyhedraled wing of the design proved remarkably easy to build and to trim. It was capable of fine ROG flights and showed good thermalling ability.

Since inspiration comes only with prodding for me I flew this little replica for a while, then set it aside for more current projects. On my list of new things to build was a Cleveland Playboy Jr. One evening I was looking over the Playboy Jr rib kit I had purchased from P&W Model Service (PO Box 925, Monrovia, California 91016) and inspiration struck again. The wing and stab outline seemed identical to the Viking. Sure enough, the surface outlines were very close and the airfoil was identical. Only one rub, the Playboy Jr was larger. I grabbed my magic ruler and calculator and quickly ascertained that a 110% factor on the Viking brought it right into scale with the Playboy.

The upshot of this second inspiration is the model appearing in this article. Granted it's a little strange to scale up a non-scale subject, but what a slick way to get out of cutting ribs! The use of lite ply for the fuselage siding produces a remarkably strong and simple to build system that gives a square frame every time. I should know as I have built three of these 110% Vikings..."

Quote: "Another one I cleaned and scaled from the pile, but don't know if this has been posted before: Viking 110% by D. Mathews 310 Nice for a Texaco event."

I'm sending you photos of the Viking 110, built by me from your plan [more pics 004-006]. The model flies very well and is very pleasant.

* 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.
