im building a profile (scratchbuilt) that is very similer to the tower fun-51. it has about the same airfoil only the wing has been extended 2 bays making it about 52 inches. (compared to 44)
the fuse has been extended about 4 inches and the rudder/elevator servos will now be in the tail. (its about 3 feet 3 inches)
heres a pic of the fuse.....
do you think i should sheet it? im thinking of throwing a magnum 46 or 52 for the engine. the plane will be for 3d (if it even flies). the fuse is made out of 3/8in balsa while the origional th fun 51 used 1/4 balsa for the fuse and it was sheeted

also should i fiberglass the center section of the wing since its much bigger?
