One type of aircraft you really experience the adverse yaw are the WW1 era. I have a Fokker DR1 triplane that actually prefers to lead with the rudder. You initiate the turn with the rudder, and just use the ailerons to maintain proper angle of bank. If you just try to fly it around with the ailerons, like most RC planes, it will skid, nose high thru the turns.

While co-ordinating turns is important with full scale, you will not find it necessary with the majority of the models you fly, unless you get into scale, and even then, only certain designs require rudder in the turns.
