Topsy - Wakefield model from 1951 March Aeromodeller.
Quote: "A new ruler Wakefield from Northern Ireland by Norman Osbourn... Topsy is the sixth of a series, the original was designed in 1947 with the intention of flying it in the Irish Nationals of that year. Hoewever the prototype was lost 13 mins 13 secs OOS on a test flight two weeks before the event, and the second version was hastily built in the odd fourteen days... Simple in its construction, yet incorporating features akin to the most efficient Wakefields, Topsy should appeal to many beginners in the classic event of model flying. It completely conforms tro the 1951 Wakefield rulings, and thanks to the tip-up tail dethermaliser now incorporated, promises a first-class competition performance for 1951..."

* 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.
