With my freestyle I can take an waterfall directly to a knife edge spin just by using a little aileron to push it on there on its side. It is not a true knife edge spin, but I think it almost looks better as the plane will loose little if any altitude. Not as tight as the KE spin. More like an waterfall on its side that just hangs there. I think i'll have to give it a name if already doesn't have one. I'm sure there is some kind of name for it.
