Bi Plane
 

I've sure i've seen a bi plane in this game, but i don't know what it is called, although i believe it is a russian plane. Does anybody know the name?

I-153 I think.

yes it is called the Polikarpov Po-2 and it is indeed a russian bi-pane

there is also the russian Polikarpov I-153 the updated version of the I-15

I-153 Chaika & Po-2 (which was actually a 1920s plane!) The Chaika is the fighter, looking like a I-16 and I-15. While the Po-2 is a trainer, bomber, and reconnaissance plane.

And there both bloody hard to shoot down with a good pilot at the stick. Arcade mode they are WAY to good at the whole turning battle, using them feels like cheating to me. Different story in Realistic mode but they are still super effective when used by a good pilot.

The I-153 is meant to be a turn & burn fighter, the Po-2 not so much. But if you want to gun down a Po-2, just come up from below, or from the top, coming down on its nose so the gunner can't get a shot ;) Whatever you do, don't turn with a Chaika, it will be your last. LOL

IS that because they have so much lift?

Its the I-153 and you unlock it by completing the single mission chapter of "Battle of Stalingrad." I unlocked it yesterday and did one training mission with it and was going to try a landing and when i thottled down to "0" the engine cut out and the prop stopped spinning and i glided in for a landing, but was unable to start the engine so i had to quit out. I wonder if it is even possible to somehow re-fire engine !!!

Nope. Thats the risk you run with flying the aircraft.

lol yep I kept doing that when I first flew it. Now ive learnt never to push the stick forward to decend, always roll over and pull back.
