RE: Spad to the Bone Dominator Problem
As said before, If not a little re-flexed make sure the ailerons do not droop. Usually if the plane acts a little squirly in pitch dialing up the ailerons smooths it out unless you really are talking nose heavy. As for that how are you measuring CG. Do you use a sling, a stand or your fingertips? Used fingertips for years but sometimes it's easier to stick it in a sling, hang it level and see where the plumb bob is pointing. I've had a couple of airplanes that slinging it really caught some of balance situations. Anyways, if it's built to plans really it should only be the ailerons that are the problem, there's dang little else to go wrong.
