A model RC / Hobby plane would have no trouble turning 360° in 2 minutes - it would have no trouble doing a 360 in 10 seconds (Ive been flying RC planes for 30 years)

but an auton RC plane with a heavy payload would have to turn slowly to avoid stalling its wings.

BTW, no offense intended but I'm a little leery assisting someone in Pakistan to design a control system for an autonomous RC aircraft. I don't know how many RC hobbyists there are in Pakistan, but I do know of other people in that part of the world who are very interested in autonomous aircraft!

EDIT: Im already taking a lot of (red) flack for my post in this thread - Its my opinion that we should not help anonymous first time posters who live on the boarder of a war zone to design autonomous aircraft.

Sorry if I come across as a jerk, but in this case I prefer to err on the side of common sense!
