The Precedent Turbulent is done the same way, hiden within the fuz, I never had a probem with that setup.
I would confess on one of my old Stampes it came to me with Sulavan snakes installed, prety much usless so for a quick fix I mounted the servos in the fuz under the tailplane and then covered the fuz with just the servo horn on show from the outside for ruder and elevator with pushrods of about 3" long, just a shame after a year or so the wings could not take the strain of high G flight.
