Your stick assumptions are correct.

I have no experience with the plane you linked, so I can't comment.

You may find, however, that a 4 channel plane might not have the rudder authority to turn the plane as effectively as you want.

Try turning down the throws or something, meaning, adjust where the pushrods connect to the servo and control surface to give you the minimal amount of throw. (ONLY on the ailerons!) Then you can adjust the rudder for more throw.

Practice using the ailerons on low settings, and you may be pleasantly surprised.
