RE: Sig Smith Miniplane
Build it to the plans and you will be happy with it.
Mine is built exactly to the plans with zero incidence top and bottom. I love the way it flies. It balanced perfectly with no extra weight, and needed almost no trim. I haven't had any of the problems with excessive down elevator trim that I have heard in other posts. I haven't had any ground handling issues either. It goes nice and straight down the runway with a little rudder and doesn't have a tendency to nose over on our grass runway.
If I do it again, I'll build to the plans again.
