X650 Development Kit experience?

Hello everyone!

I’m going to buy this kit, but I have a couple of doubts and questions, the answers to which I can’t find from the seller, maybe someone knows?

  1. Has this assembly been tested? Where to watch or read?
  2. do we need any settings so that it just flies and performs simple missions? Is this build ready to use?
  3. was PID and Pixhawk setup done?
  4. Is it necessary to adjust the engine regulators separately?
  5. How is engine calibration done?
  6. Will there be assembly instructions and does anyone have experience communicating with technical support at Holibro during setup.

Thanks in advance!
Eugen
