RE: seagull extra 300 or edge540
I don't remember making any major mods to mine.....aside from stuff like fuel tank, wheels, hardware.
By the time the plane snaps, you'll KNOW you were going to slow. On your first couple of landings, you might drop a wingtip if you slow down a bit too much, but it's easily recoverable when this happens. You'll get the feel for the landing speed pretty quickly. It doesn't land hot, but it's definitely not as slow as your Ultra Stick.
The control surfaces are EXTREMELY effective. DO NOT exceed the recommended elevator throw until you are very comfortable with the plane. It's very effective.
The control surfaces are very deceptive....they look small, but are very effective.
