If you need a quad for Ariel photography then i would suggest a s500 quad or if you can afford a hexcopter for more reliability.
A S500 frame supports bigger motors which mean bigger props as well.
Thank you Mr Balakrishnan for your kind reply and support but please can u suggest me which one will give me more speed if I will use 980kv motor with 1045 prop on F450 frame or a 1000kv motor with 11" prop on S500 frame. Thanks in advance
