Another data point on elevator balancing is that Troy Petteway deleted his elevator balance when he lengthened his horizontal stabilizer and decreased the length of his elevators. I know he's done over 230 mph that way, so it's looking like that's been pretty well tested. See the fourth picture down at http://www.n56ml.com/troy/ for exactly what he did. He reports a big improvement in the pitch sensitivity situation with these two simple changes (tail dimensions, although deleting the weight back there would have contributed as well).
I've done 235 mph or so, with the "new tail" airfoils but mine is still balanced. Given what I know now, I may not balance the elevator on my next plane... Mark Langford, Harvest, AL ML at N56ML.com www.N56ML.com
