Hello, welcome to Cnczone, it is good to see you here. There is a lot of good people and information here, hope you like it here.
Either way will work just fine, if you have a good set of boards and motors now. It depends on which way you want to go.
You may feel more comfortable typing in French, and maybe I can translate a bit and help you out.
Forgive me if it takes me a bit to understand, I have not spoken French in a few years.
