I guess, after reading another post, I should let you know the kind of flying I am planning to do.

Seems to be pretty important on the kind of first plane to get.
First of all, I want to learn how to fly, but I don't want to just go round-n-round. So after gaining a little competence at controlling takeoff, level flight and landing, I want to get into some mild aerobatics, loops, rolls, barrel rolls, chandelles, etc. Now from what i have read, and remember I have only flown control line and my little Viper (throttle and differential thrust) I think I should go with a four channel set up from the get go.
Does that make sense? Or am I missing something?
