About this 3D model

Improved version of previous FPV Blended Wing Aircraft. Now comes with a central body large enough to carry all electronics and camera systems. Still in early design but If anyone can offer advice for improvement that would be great since I don't have a 3d printer and can't optimise designs for a 3d printer or for filament types just yet. Motor mounting is not bored our in the back of the aircraft so that fittings can be changed for any motor needed. Please comment on anything you would like to see improved or altered if you wish to do so.
