All of those high horsepower monoplanes had all sorts of torque problems and could easily do ground loops. Most had terrible glide slopes and required horsepower to keep them in the air. They definitely aren't for the faint hearted. I think I just like to have one to work on and look at. I have no desire to pilot anything. Even their RC scale brethren have the same lousy flight characteristics with high wing loadings. It's like the difference between the B-17 with its big fat wings and the B-24 with its more advanced shorter chord wings. The 17 was much easier to keep in the air when damaged, unlike the 24. Another example: the A-10 Warthog. Slow and low with everything redundant and lots of lift. Hey... isn't this a model railroading forum?
