Well, i want to get int rc flight, i really wanted a heli, but the planes are wayy cheaper and simpler, and i think i'd crash a heli alot. So, i'm at tower hobbies looking at rtf's and i need some help. Ok, i narrowed it down to a few and i need to know which is the best of the ones i list. Well, my first question is, what is it called when you can with the radio go up and down. I don't want a plane that tou have to set it and not be able to change it while in flight, so i want to know if any of these have that funcion also, because my grandfather purchased one with that pre adjusted before flight, and he just hasn't run it since because it's a pain i guess. I might pick up another cheap one while i'm at it just so he can fly too. Do all 3ch planes have this function? Here's the links.....
Oh ya, and how much runtime will i get with the stock batts?
