And the Great Planes Siren Hotliner doesn't even have a rudder and banks/turns fantastically well. If I were to use rudder along with aileron to bank my 4*60, the plane would land, roll over to me, grab me by the throat and say: "RUDDER with aileron to bank?!? What the heck do you think you're doing?!?".
Yes your plane will turn just fine without rudder. After all. Roll is the primary effect of aileron.
Rudder just provides that last ounce of finesse by balancing adverse yaw. In most RC models you will never notice the difference.
You do notice it in real aircraft by the seat of your pants and the balance ball.
In slow flying aircraft such as a scale ww1 bi-plane you really notice a big improvement in how they roll into and out of turns if you use rudder to counteract the adverse yaw.
