Simon, give some thought to the control linkages, especially on the elevator, I cut out a bigger slots so that I could uses to shortest hole on the servo arm, I think JRI made new taller horns for his control surfaces. if you go with the setup as instructed in the manual you will have enough control surface throw to 3D it! But if you have no intention of doing that then you effectively throw away a lot of the servo travel reducing the precision.
But I am basing this on my MythoS 50, but looking at the manual I think the Wind S and MythoS are essentially the same in this respect.

Oh and I spent ages faffing about with trying to get the rudder on a pull pull system, because I felt I could not get the CofG right with a servo in the tail, in the end I could balance it with a servo in the tail, which for me feels better. But different servos and batteries are different weights so play around and see what looks like it will work for you.
Another thing, if you're happy to spend a few pounds, try a Sullivan tail wheel bracket rather than the one provided, I think it reduces the pounding the rudder servo gets as the tail wheel bumps over the rough ground.
