I dont know about everybody else, but I have never had a problem with my edge (except for crappy landng gear mounts). My edge with a saito 180 has never tip stalled on me. Now there is significant wing rock during harriers, well, make that a lot of wing rock, but it is not enough to prevent it from landing in harrier attitude. I can slow this plane down to a crawl, but it doesnt tip stall. at near stall speeds, the wing will begin to rock a little and then the nose wil drop, unless for some reason you add more elevator and then it will tip stall. I cant speak for everybody. Many people have claimed that their edge isnt worth having, but mine is great. Also the dave patrick airplanes do look to fly a lot better. They dont wing rock at all during a harrier.
