About this Plan

Thunderhead - Towline glider model.

Quote: - "A/2 Nordic soaring is a glider event for the best of competition. Beautiful graceful gliders that sense-out every breath of rising air, and make the most of it. Trouble is, these refined aircraft tend to discourage inexperienced builders with their intricate wing structures, undercambered airfoils, and reliance on grade-A-perfect wood for assembly.
The 'Thunderhead' Soarer is not an A/2 in this sense, not intended to best the competition, nor is it in the same league at all. It is a fine trainer. A less-complex soaring glider of ample proportions, with a flat-bottomed airfoil and squared off wing design. It is intended as a more easily built design with which you can gain an introduction to the sport, and formulate a few of your own opinions as to what next to build in the way of a contest machine.
The wing could not be easier. While it appears well-ribbed and complex, all ribs are stripped from sheet with one simple template, and spars cut from sheet to the heights required. It makes a light, strong wing, easily assembled in one day from start to finish..."

* 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.
