Well, since it's free, you can't really go wrong, assuming you're referring to the Milton Shupe (SOH) F7F. Beyond that, if you're familiar with the work of Milton's team, you can't go wrong there either, including the fine air file work from fliger747, who has been doing this sort of work for a while now... Recommend it? Yep. What is it like to fly? Well, best I can tell, like an F7F!
