I've got to ask.....since this is the beginners forum...what are you flying that you need to mix rudder with aileron?.....If it is a simple matter of making better turns then practice flying with your thumbs.....if you are a beginner you will be a better pilot in the long run for not using a mix like this...another good practice for rudder and aileron is a flat turn..start with rudder then use opposite aileron to keep the wings level
