He can also take a look on the "Federation Française d'Aéromodélisme" website:

It's the french "AMA".
He can find all the clubs in his area from this page:

(Marseille is #13).
I'm french but never flew in France. I had lived abroad for the last seven years and just came back to my country a week ago. I learnt to fly in Canada.
