maybe a simpler (possibly wrong) way to explain this is just watch the fuselage during your turn. if it seems to be really nose high dragging the tail through the turn, a little rudder to compensate will level out your fuselage. if the nose is dropping, then some opposite rudder will put things level again. kinda the thing you need to just play with to figure out how much is enough or too much. depending on how steep your bank is, the more elevator you pull (if you are in a steep bank), the tighter the turn will end up.
