I am working on a UAV for a project at my school along with 4 other friends. We have the computer/gps/ camera figured out but i am still not sure on the plane. Was wondering what the average 60 size trainer could haul around. I am estimating at least 3 extra pounds of weight. 1 pounds for the computer, 1 pound for batteries, and 1 extra pound for fuel (need to get at least 40 minutes of flight time). We are thinking mag 91 on the hobbico mk11 60 trainer. Any thaughts? Also thinking of using the FMA co-pilot to assist the computer and keep it steady for the camera.

Thanks
Cameron
