Hi!
Those planes are more or less "toy planes"!
What do you want? Learing to fly ? Becoming a full fledged R/C pilot or just ocassionaly fly?

Best way of learing is joyning a club (becomming an AMA member)and see what the club members fly. I believ most members of clubs fly larger planes (Glow powered..and electric) as those are easier to fly than the small ones you mentioned.
Of those you talked about the "Radian" is more simple to learn on, provided you get help from knowlegable club members that is. Learing on your own is always going to end in a crasch!
