Many WW2 aircraft just have castering tailwheels. This is ok as they have brakes. A castering tail wheel on a model does not work, I tried it! lol I just wanted to point that out.
I always wanted to try the fixing the wheels to the axel trick, and I may possibly try Toe out one day as well. I am open to anything that helps. My Tripe does ground loop about half of the time. Mainly because of the wind.
