Where ya gonna put the servo? In the main part of the body? Or in the tail right after the bend?
In the tail right after the bend would make setup easy but in the pics it looks like those are built (profile like). Wouldn't want a servo pokin out the side. Hitec makes an aileron servo (thin and flat). One of those might fit.
I'll bet the guys in the scratch building forum will be interested in following this build.
