The radio transmission signals will not pass through carbon fiber. The 'cockpit' area and nose of the fuselage is made of regular glass-fiber because that is where the radio-control receiver and other electronics will be located. The kevlar strips are laid in the stress areas that need reinforcement for strength in case of nose first impact, but overall this area of the fuselage is far less stressed than the boom/rudder and lifting surfaces of the wing where carbon is used.
professional Fuselage build ? No bolts in the molds, connecting with screw clamps like in stone age, not possible to push/close the mold due to the rising inmolded peaks. no white Gelcoat on the fuse, take out and fuse is ready. This is not state of the art in Mold and Fuselage building. Carbon looks good but not necessary. area fuse/rudder is immensly stressed and will break.
I think the wooden frame is a good idea on such a long mold, to stop it from warping. Makes bolts redundant. Metal frame is also an option. But I think you'd be being a bit too harsh. They probably know what they're doing.
