I would only add that if you want windy weather performance go with a semi semetrical section, about 16-18% thick. All correct assumptions, power to weight ratio, not lift, and long tail moment with generous tail volume.

I also tow behind a quarter-scale Wilga, which has a flat-bottom Clark Y type airfoil. Another popular tug is the Piper Cub, again with a Clark Y. I believe you will find that the chosen airfoil is not the most important parameter for a good tug. RCSE-List facilities provided by Model Airplane News.
