That doesn't sound completely normal but there are too many variables to give you a logical answer. Have someone else look at your plans and do a complete W.B. independent of yours and see if they get the same answer. Don't let them see any of your numbers before they start. What type of gear do you have (Diehl, Grove, retracts, etc) and do you have a picture posted somewhere? How far forward of the wing lead edge are your axles with the KR in the level position? The tail should come up much easier on the roll as it is primarily the lift of the main wing that brings the tail up to level. Anyone that doesn't believe that should watch the elevator movement / location on a taildragger on takeoff. Rolling level on the mains the elevator is very near nuetral. The center of lift is close / behind the CG and all forces must be in balance at flying speeds. The rudder and elevator are really just large movable trim tabs. The horizontal and vertical stabs act as fixed trim tabs. Larry Flesner
