I am not sure what level of flying you are at but later on with a good radio you can mix aileron and rudder together so when you turn both parts will become part of the turning motion. Not so important with the smaller planes but some of the bigger ones need a mix to get them round corners. I have a large ESM Beaver that flew like a pig until we got the mixing correct.

With a modern good quality radio you can mix all sorts of things together so if you need or require it you can mix aileron and elevator to help get you around a corner a bit easier. I have a pylon racer with aileron and rudder mixed together and am madly reading the manual to work out how to mix elevator in there as well. When flying at 120 miles an hour on a short circuit need to keep it as simple as possible.

You can do all sorts of things with modern radios just need to read the manual and work out what works best for you.
