Running through the books again and found a little nugget that caught my eye. Higher AR surfaces stall at a lower AoA than low AR surfaces - therefore, you want your HS to be a lower AR than the wing. Makes sense. You don't want the HS to payoff in the flare like the early Cardinals did. So, is there a rule of thumb for the relationship between the wing and stab, or do both surfaces need to be analyzed independently?

I bring this up because the Lancair Evolution has a constant chord stab of fairly high AR. This is appealing to me from a construction standpoint because I can make one mold which will work for left/right/top/bottom skins.
