As you prop can see i am new to this site and "hobby". lets start.... i am busy with my own UAV design and project but from what i have red there is a lot of stuff you should consider in building your own UAV. Sooo much calculations i am brain farting ;) !! Just one question my design is.. length of the aircraft is 1.5m and 20cm in diameter now i want to know what WINGSPAN would work best on that length of an aircraft and what should the wing cord measurement be....Any help would be much appreciated. Thanx in advance.
