2212 motors with around 1000kv
350mm or bigger frame
20-30amp esc's & decent amp pdb about 120-180amps.
10inch props.
I think the bigger the platform/frame,
The more stable it will be.
This could be achieved on a smaller quad but not for very long.
What length of flight time is required,
Though for a 350mm - 450mm size frame you would be looking @ around 4000mah max. For 3S or 4S.
If it is just a project then have you any flying experience. I fly barebones acro so if you will be needing autonomous flight & GPS, I'm not the guy. If your only going to fly it a few times you may get away with just a naze32 fcb. If planning any use afterwards it may be worth forking out for a decent fcb or atleast get a
seriously pro racing F3 board.
