Sometimes they are done together as in the case of the old lady in the TV commercial who say's "I've fallen and can't get up!".

However....It's good to see a discussion in the beginners forum that centers around the use of rudder. I know several turbine pilots that don't keep a hand on the left stick while flying, just pathetic. Flat turns, slips, flat figure eights upright and inverted, will all make you a much better pilot.
