Thanks, I was thinking of building/acquiring a S7 STi and they don't seem that fast with the big tires and I don't know how much of this is the tires and how much of this is the wing.

Just watching YT Video's such as Trent's and others with a 100 hp (minimum) engine and they are cruising in the 90-100 range and odds are more often closer to the 90 than the 100.

I do not care about meeting the LSA requirements if this matters. I see a lot of comments on this site in reference to the LSA rules but I don't have a sport pilots license so I don't really care. I'm out for fun not a loop hole to allow it.

I'm still in the planning stage and I don't even know if a KF is the best option for me. I want a STOL plane and I have a distaste for a tandem setup so side by side options tend to be between the KF and the JUST.
