THanks all, yea last night I've given another thought and decide if I join a club I'll buy the 4ch TX first, the Quattro one most probably (that's just because I don't know other TX )
And if I'm not mistaken, in the club I'm thinking to join, they offer 2 free lessons or 2 free visitor pass to try fly the plane.

It's good that this hobby is not time consuming. Now Another thought, where do you keep your planes? Even if it's a scale model, it sure does takes some spaces
