Hallo Oliver,
the german training aircraft for fighter pilots was the Arado Ar-96b.
It was the german counter part to the american North American T-6.
Also where used after the dedeat of France several ex-french fighters,
as the the Morane 406 and the Dewoitine D520.
As primary trainer the Luftwaffe used the Bücker Bü-131 Jungmann, later the
Bücker Bü-181 Bestmann.
You will find all these planes here in the SOH library or at flightsim.com
apart the Bücker Bü181 Best mann that I know only as a payware from Lionheart Creations.
Laterr near the end of the war The Luftwaffe used some few two seater versions of the
Messerschmitt Me 109 (Me 109 G-12) and the Focke Wulf Fw 190 (Fw-190 S).
On my knowledge sadly there are no Flightsim versions avaible of these two birds.
I hope that my little indications might help you.
Happy landings
