Hello,
would you taste the emotions to fly with the aircrafts that you know as model?
http://riseofflight.com/en is a very good WW1 aircraft's videogame in which you can fly vs Computer or other gamer, online.
The aircraft's textures are really good, the fly Physics are almost perfect and the aircraft itself has a very good fly-mood.
It's not for free, for it's a very good accurate
simulation (not a simply game) but you can download a Demo, with a couple of aircraft, to see what's in the game.
I higly recommend it: it's the unique WW1 aircrafts simulation that really works.
EDIT: You can find a lot of videos on Youtube about how to fly or simply how to turn on your aircraft. Also combat manouvres and acrobatic ones.
