Sam,
I am trying to decide what to use for my tail wheel. I see you used the Sierra Giant tailwheel. I have both the Sierra Giant tail wheel and a Robart tailwheel. I'm tempted to use the Robart tailwheel as it is much lighter and I don't see any difference as far as looking scale.
Is there a reason why you chose the Sierra Giant tailwheel over the Robart tailwheel?
PS - Your work is unbelievable and I am so glad you have documented your work in such detail. It gives a first timer like me more confidence.
