Thanks MJSteve. I have snuck a peek or two at the book at my LHS but at $35 not sure I want to buy it.
I think it shows the servos exposed under the wing and what I'm after is mounting them sideways inside the wing with somekind of access hatch. Think that would look a lot cleaner.

A photo or drawing(Minnflyer you got your ears on buddy) from someone whould be a great help.
