I have the speedster wing on my 4. actually it's a long wing cut down. I have dihedral in the wing. I can consistently land within 300ft. in fact my last landing a couple days ago I landed much shorter than that with calm winds and didn't even try. I think the big key on landing short is to be able to control your idle. I can pull hard back on my throttle and get lower than 2000rpm. what that does is cut out that float. so it's all up to the person flying the thing as for what is really going to happen on a short landing. I don't use flaps either. I know, people have tried to argue with me on that one. I love the light stick on landing with my electric trim in the back. I can't complain about my landings or take offs. I'm also not out to do stol competitions, just go out and have as much fun as I can. I also have 27.5 tires and spring gear and cruise at 115mph.
