i guess what im trying to figure out is i have seen on some planes the elevators (looking from tail) and (dual servos) move up and down (for take off and landing) and during 3d flight thats is where they are split one up and one down can that be acheved on a 6 ch tx or is that just a great function on higher end more channel tx (((because when i move my elevators they both move the same up and down))) maybe thats a more clear question than what my topic is about thanks guys for all the info
