Rudder size effect on control

   When deciding how big or small (surface area) a rudder should be,
what behavior would you see if the rudder is too small? I guess there
would be a point that big enough is enough and then you just gain
weight if you continue.
   I've seen a stable flying model under power suddenly start to rock
and not turn so well in the tail end of the cruise phase and wondered
if it needed a larger rudder. Not more angle (drag), just more area.
   Any thoughts? thanks
