Plan file details

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..." Direct submission to Outerzone.
