I would take some flights and play around with the rudder to get used to how it works and what it does.
that way when you need it you will be comfotable with it.
set the wind in g2 to 90deg off the runway about 5mph and shoot landings useing rudder to help out.
but i wouldnt worry about it on your real plane until you are comfotable with useing it on the sim.

here is also something for the expierianced and new pilots to try in G2.

take the lt40 and make a copy to edit.
go to engine and take out all the downthrust and add 2.5 deg right.
exit out then add a few clicks up on the TX.
now take off, fly a figure 8, and land on the runway without touching the right stick.

you gain speed you "balloon" up and use the rudder to turn... but you balloon to far and you run out of airspeed and fall also you need to accelerate in the turns to keep altitude.

good practice for useing that left stick.
