Polliwog (oz11609)
About this Plan
Polliwog. Rubber competition model.
Note the original Willard Ballou Polliwog design dates back to the early 1940s. This here is a later redrawn plan, circa 1986, by Terry Rose.
Quote: "This drawing was made by Terry Rose from Willard Ballou's model which David Baker brought back from the USA in July 1986. Since making this drawing I have had a letter from Willard enclosing a rib template which is exactly the same as the section I drew from the model - the section is Chessman 25-100-10. He has also used NACA 6409 with equal success."

Note some sections of text on this scan are hard to read. If anyone can submit a clearer scan, that would be great [this is fixed now, see below]. Steve.
Update 29/10/2019: Replaced this plan with a clearer copy, thanks to theshadow.

I believe this should be a 45" span (not 35") as I think it was a Wakefield. Also, I believe this had a single mono-wheel landing gear under the leading edge (see magazine image on person's arm). If it was a Wakefield, it required landing gear for ROG.George Bredehoft - 03/03/2023
Not sure. The drawing seems good overall, I mean it seems to be scaled correctly. We can check the dimensioned 1/2 in TE stock, also the prop shown measures 16 in diameter, which matches the dimensioned 16 inch prop black shown. Looks correct. Also the drawing is by Terry Rose, who seems careful and reliable. Maybe there was more than one prototype model built by Ballou?

This design was issued in alternative sizes including 8oz Wakefield. There was a big fuss in the late eighties/early nineties when david baker brought the model and plan back from USA, a couple of the top Wakefield flyers built one but it never really took off (ahem!) over here.

I watched David Baker fly his Polliwog at Taft and at Mile Square when the English fliers came over for a 50th Wakefield anniversary in the early 80s. The model flew well and is worth building. That said I didn't see many people making that particular effort.

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.
