Why do I need ardupilot orange cube?

Hi, I am beginner. I have bought pixhawk 2.4.8 . As far as I understand it is a flight controller. Si, do I need to buy ardupilit orange cube? Can I fly without orange cube? Apart from that which ESC can I connect to pixhaek 2.4.8? Can I connect speedybee esc?

Hi Serhii_Bilyk, The Pixhawk you have IS the flight controller - as is the Cube. They do the same thing in different ways. You don’t need an Orange now, unless planning to build a second drone. GL!!

You need to start at the very beginning…
Ardupilot
