VTOL Quad Tailsitter - Fixed Wing UAV

Hello everyone,

I’m currently working on a VTOL Quad Tailsitter drone, utilizing PX4 as the hardware and PX4 1.13 as the firmware. For the airplane reference, I’ve opted for the VTOL Quad Tailsitter with the following specific outputs:

  • MAIN1: motor 1
  • MAIN2: motor 2
  • MAIN3: motor 3
  • MAIN4: motor 4
  • MAIN5: elevon left
  • MAIN6: elevon right
  • MAIN7: canard surface
  • MAIN8: rudder

I’m seeking information regarding the minimum number of required actuators and which among these actuators are considered optional and mandatory. Any insights would be greatly appreciated.
