hi people
I'm working on my own design of a UAV for aerial photography i have completed the main wing design and calculated the various wing parameters for my drone but now i have a trouble in deciding the length of my fuselage it is basically going to be hollow cylinder with a thicker section till the trailing edge of the wing and gradually narrows down from there to the tail but
what should be the length of the fuselage after the wing's trailing edge?
how is it going to affect the pitching moment caused by the elevators?
how do i determine a relation between the fuse lage length and the elevator and rudder dimensions??
Please help!
if any details of wing parameters are needed please let me know

question is it a conventional or a flying wing?
if its a conventional aircraft then the longer the fuse the more stable it is on the pitch and yaw gives the tail more moment arm.
for starters a glider type craft would have 1/2 on the horizontal stab length to the fuse
rather guess work maybe you should get existing aircraft designs as reference to your dimensions. that betters your chance of a successful flight.
yes it is a conventional aircraft indeed...! the only thing i wonder is what reference can i use to decide the fuselage length does it depend on any of the airplanes parts like wingspan or the gross weight od the airplane etc??
