Well, they ain't gonna make them a whole lot faster, I think a lot of that is just
natural "drag" you're going to feel on any property those sizes, mine does 12+ mph
and on the street it feels as fast as a car...
My Z moves so good that if I come to a quick stop, the air coming up behind me
washes over me as it catches up and I can feel the breeze lol, so it is wild fast.
But sure enough even on properties as small as 3 acres, even if I do most of
what I can full stick and push it hard as I can, doesn't matter, it "drags"
So I think you're feeling some of that, mostly...
