I did a Super Stick 40 not long ago. I did remove a little material to allow for more elevator travel. As a matter of fact, I flew it on high rate elevator all the time. I just wasn't comfortable with the throw on low rates.

My tank was junk and it "blew a leak" the first time I filled it up. Trashed it and got another. Just was not worth the trouble.

A tip for flying this plane: Don't hold in a lot of up elevator while taking off. Doing this will actually "HOLD" the plane down on the ground. Instead, at about 3/4 throttle while the plane is approachong rotation, give a little up elevator and she rises up nice and smooth instead of straight up.

Just my .02 worth
