1/2A Sky Squire. Radio control sport trainer model.
Quote from Richard Browning: "The 1/2A version 39in span and a 48in span Junior Sky Squire (oz5322) version were both published in American Aircraft Modeler June 1969 issue. The original 57 in Sky Squire (oz10563) was first published in the March-April 1966 Grid Leaks Magazine ...The late R. Jess Krieser designed all three versions the 57 in was kitted by Midwest Models. Mr Krieser also designed many of the early Carl Goldberg kits (Falcon, Skylark, and Skylane). The plane was ahead of its time very attractive easy to build and I don’t think and modern sport trainer has anything on it. My first successful R/C model after a few failures using single channel escapement equipment was the 1/2A Sky Squire with a World Engines Digit Midget single channel ($69.00) for rudder only and a TD 0.51 it flew great ...I hope we start to see more of these aircraft at the field they are truly a great design"
This is a modern CAD-redrawn plan. CAD by Richard Browning.
Note this drawing seems to be a reduced scale version of the 57 inch Sky Squire (oz10563), in the sense that it was reduced by Richard Browning and not by Jess Kreiser. Looking at the (low res) original 1969 article pages, the original drawing shows a flat bottom airfoil at the wing root. But then again, it also shows some (optional) symmetrical ribs. So frankly I am unsure how faithful this planfile here is to the original 1969 design. If anyone out there can supply a good clear scan of the original 1/2A Sky Squire, that would be great. Steve.

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.
