Joe, You maybe ment this for Justin? He was asking the question about elevator balance being distributed evenly across the span. Please enlighten as to how your answer relates. As to propeller spirial slipstream, I built my KR with "zero - zero" thrust alignment and the vertical and horizontal stabs both set to "zero" alignment and it flys just fine. The greatest effect I've ever noted on propeller spirial slipstream is that one side of the airplane gets dirtier than the other on a grass strip. :-) Larry Flesner
