I can tell you that with exceptionally strong crosswinds and a forward C of G you can run out of elevator authority in the V-tails
I have also read that elsewhere. Don't know about the earlier models, but it would be a challenge to load a V35B anywhere near its forward C of G limit.
Full fuel and Chuckles and I up front get nowhere near it - full fuel and 235kg in the front seats puts you on the forward limit!
