Our club's Hog builder and flyer's routinely cuts the dihedral out completely on all of his hogs. That is his favorite plane & it seems he always has on. Nice gentle flying plane with 70 or 90 4 strokes. Of course he does have that little takeoff maneuver he likes.....about 4 feet off the ground he snaps it inverted and climbs out inverted....like I said nice gentle flying style. Andy
