From my experience:

the fancy holes on top of the wing panels are for two screws that secure the wing tube in position

hinges, I think they left this for presonal preferences. great!

Fancy hole in the back of the fuse, is for painting reasons, to hold the fuse somehow. it will be hidden below the rudder so you cant see it.

split rudder: I agree, (I dont use it) but, if all of us use al least a 200 oz. torque servo for the rudder, how can two mini servos do the job?

Elev servos, do what you want... I think this is great, use you prefered method. you are not restricted to the manufacturer choice.


best regards.
