I'm new in the community.
So the question is in the title : Why there are no more cheaper flight contollers available ?
Actually, if you want buy a supported hardware you have to pay at least 100 $. Tell me if I'm wrong.
While you can find flight controller for 40 $ on any RC provider such as the SP racing, the flycolor, the racerCube...
Is it because they are not enough powerfull ?
