The 109E-4 is considered quite slow, being as slow as the Spit Mk.I and only marginally faster than the Hurr Mk.I.
It does not accelerate overly fast compared to any post-1943 aircraft, nor does it outclimb much, either.
It has a small turning circle, but if the enemy is in a plane with a stronger engine they only have to get you slow and then climb over you and roll back down to kill you.
It is a fun plane to fly at times, but your victory over 2 chogs at once was a fluke. Any halfway-decent chog pilot can kill a 109E.
If you can get your opponent to slow down into a stall fight, you will have a fun time killing them. Otherwise your chances are slim that you'll get a kill shot.
