I am wondering if anyone have try mounting the engine for this kind of airplane in the middle of the fuselage. I saw many plane mounting the engine in the front of the fuselage and some even in the back of the rudder. Any of you ever try mounting the engine inside of the fuselage right in the middle of the airplane? I mean that the prop will be inside of the airplane just like those in electric ducted fan type assembly. I am trying to build something new. Any one with this type of experience or have any pictures to show would be very much appreciated. Sorry if I didn't use any aircraft term since I am not good with aircraft terms.
