About this Plan
Tadpole. A/2 glider. TADPOLE A/2 glider by Peter Law, Aeromodeller July 1953.
Quote: "A high performance, modern trend A/2 with minimum wetted area, high aspect ratio nad simle structure. Tadpole, by Peter Law.
FIRST designed early in 1952. the original 'Tadpole' was never flown in a contest until the '52 A/2 Finals at Digby, when, due to over-careful pruning of the DT fuse, it returned a 14:26 total for sixth place. A second version, flown by R Law, placed fifth in the Thurston, at the '52 Nationals, and a third was flown by D Ridley in the Trials at Kidlington this year, the designer's own job having been lost earlier on in the eliminators. A still air average time of 4:20 on a 328 ft line has been attained by each of the three models to date, and top-of-the-line tows in any conditions have proved standard practice, factors which put this semi-pod and boom job into the top bracket.
The relatively high aspect ratio of 13:1 for optimum efficiency, demands that for general portability, the winghalves should be detachable. Tongue and box fitting was selected, both for its 'knock-aff-ability' and sure method of obtaining identical incidence for each wing panel. Tongues which appear to loosen up in warm weather can easily be dampened and so expand to make a desirable tight fit into the wing boxes.
Construction commences by building two sides over the plan; these are removed, sheeted before separation, to prevent distortion. and joined at the wing tongue, checking squareneas. When dry, install tongue, auto-rudder trigger, and towhook, cementing securely..."

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.
