Food For Thought

Recently while doing a rebuild on one of my axes, I noticed that the tail pitch slider is off center to the right ( looking from the rear ) where as on my CX and B400 the slider was left of center. The heli flew just fine, no discernible bad habits that were not pilot error. On closer inspection I noticed that the control arms were on the leading edge of the tail rotor blades. Now based on my auto racing experience, I know that there is a significant difference in performance depending on the track and surface type between a front steer (control arm ahead of axle) and rear steer (control arm aft of axle). I am using align metal tail rotor assemblies on all my birds that have a driven tail. I have since switched the axe tail back to trailing edge control (rear steer) just for consistently, reversed the servo and now good to go. On all the helis I have seen, which in the grand scheme of things is not very many, All the main rotors and tail rotors are trailing edge controlled.
I am not at the stage where I am doing any kind of 3d flying, just basic forward flight, simple hovering and working into FFF. So my experience in flight is limited. Getting to be an expert mechanic tho.

My question to this thread is.... Is there a significant performance or mechanical advantage to using trailing edge control as opposed to leading edge control??
