I just bought a Hammer 40 short kit and from the looks of it a lot of people here have had Hammers so I'm hoping I can get some advice.. One thing that surprised me since it is advertised as a pattern plane is the length is only 80% of the wingspan. I'm thinking of adding 6 to 8 inches in the fuse between the wing and the vertical stab and possibly 2 inches to the nose. Has anyone here done anything like that? Also, the plans call for some dihedral in the wings. Has anyone reduced this or taken it out?
