I would have to say that I don't agree on the need for stab balancing in our models. Not one of my jets have balanced stabs. That includes 3 x F16's, 2 x F18's, 2 x F15's and an F14 and 20+ years of flying jets. They all do several hundred K's per hour. What is far more important is to minimise control surface slop and that comes down to tight pivot mechanisms, slop free linkages and powerful precise servos with the correct geometry (longer control horn on the surface and as short a servo arm as possible)

Hope that helps. Flame suit is on.
