I'm in the arena almost every night so I guess any night is fine. as a precursor to engagement here are some pointers on the one-oh-nine. we can work on application any time you see me on.
1. disable the stall limiter and combat trim. when in a dogfight trim full up elevator. this goes for any ride in the game. trim control is what allows the savvy 109 player to follow any diving ack runner and often rewards the 109 enthusiasts with comical questions like "how can a 109 keep up with my runstang in a dive?" the implication being that 109ist is teh haxxor.
2. you must, must, must be working the throttle. the yank and bank acceptable in a spitfire or hurricane will simply not work. it doesn't work in those planes either if you come across a player who knows how to play but in the 109 you will be dead in a half turn if you don't work throttle.
3. you must, must, must work flaps. the timing for flap deployment will come to you with experience, timing is very important as is having the correct amount of flap for a given E state and anticipated manuever.
4. you need to have soft hands, the 109 will greatly reward precise delicate and smooth control imputs.
5. start by playing with 100% fuel. in my opinion nothing teaches proper control imput better than wallowing around in a decidedly overweight ride. if you can master a slow and heavy 109 for even a few turns against the good players in the AvA that in and of itself is a victory.
there are some other suggestions I could post but these are sufficient for the novice to begin with.
