I learned really quick that if you pull the rudder into a turn, while trying to make a slightly tight turn, you go into a stall! WTF I would think it would sorta counter it since I was going at a fairly good speed to make a tight turn. (I didn't pull the stick into my chest or something like that.)
But also, I've come to realize on the Battle of Britain missions, who is friend or foe by how dark they are against the clouds. If I see them well enough, then its probably a Hurricane or Spitfire. If I lose it once or twice against the clouds, then it's a 109
Seems to work for me as my little theory/experiment only failed me only twice.
