RE: 4*40 Tail wheel ?
I agree with you, I dont like the idea of the landing force concentrated on that lower hinge. It will work depending on how well you can land your plane but I just dont care for that set up. Go with a Sullivan tail, it puts the load bearing on the aft fuse with a coiled spring to the rudder-the best method I use on all my planes. This also puts less stress on your rudder servo as well. Good luck and the 4* is still one of my favorites.
