Building an Advertising Drone

Hi there,
I am designing a drone for advertising purposes,
It would be very much similar to the one showed in below video:

But instead of a cheap quad (used in video) I am planning to build a Hexacopter and surround it with advertising frame.

For that I have shortlisted some parts for which I need some feedback.

  1. Sunnysky x4110s 340kv motor
  2. 17 inch propeller
  3. Hobbywing xrotor 40a ESC or tekko32 35 amp ESC
  4. Tattu 10000mah 6s 15c (will 15c be enough?)
  5. Pixhawk cube with here GPS
  6. Custom built frame for hexacopter
  7. Expected payload weight 1.5kg

Thanks in advance
