RE: 4*40 Tail wheel ?
I've used the tailwheel mounted in the rudder in several planes with no problems. The SE was the first to break. It was the ARF version of the SE and the hinges weren't the regular Sig Easy Hinges, they looked completely different. This different hinge could have been the problem. Still, I think I'll use a Sulivan or Dubro tailwheel on the SE kit just to be safe.
