Could anyone who has considerable acro experinence give me an answer to 2 questions? And any informed opinion is fine.

1. Is there a max wind limit for an acro contest, with the usual planes, Pitts , Yaks, Extras, Decathlons, etc.?

2 If someone is doing a half cuban 8 in a warbird, say P-51, or T-6, what g force do you think they reach?

Thanks
