In an ideal world yes. That point is about 120mm as recommended by Sebart. However, on some model this doesn't balance the model properly and you end up with a lot of elevator up trim to get it to fly straight the right way up. I suspect it has a lot to do with the what the angle of the horizontal stab is once glued in - which probably varies if my model was anything to go by. I had to use 2mm balsa between the fuselage and the stab when gluing as the gap was just too big.

I'll keep testing and moving the CG further back. I'm currently just over the 120mm and has quite a way to go yet.
