Don't know why the previous posting was deleted, perhaps the person who deleted it could tell me why?

Anyway, I was trying to determine if it is better to have an all flying tailplane pivot along its aerofoil centre line or pivot from a position some distance away from the centre line as per the image. I am building a 1/6th scale BAE Hawk and the fullsize pivots along the aerofoil centre line. I have also looked at a couple of other similar models and they don't pivot below either.

I know the pivot method is used on some T tail gliders, but is it best practice for a heavy jet (20lb)? I am concerned at the extra possibly unnecessary force applied to the servo trying to move the tailplane with an already built in turning moment. I am told that jets suffer from large loads on the elevator, so anything that can be done to reduce that is welcomed.

It was suggested that being at the MAC point is more important than the pivot moment, is that because it reduces the moment, or what?
