Good to know you are interested in learning to fly the right way. With only one month under your belt, I guess you can expect to have a few frustrating days and nights to come, but in this game, I believe everyone has had to go through that. I would have to think most of us still have those "off" days.
The most forgiving 109 to fly (other than the E) would be the F4. However, like any 109, flap management is very important.
Anyway, I wont overwhelm you with information. You will quickly find that you will start learning the more you die and fly. With 109s, the one piece of advice I found very helpful when I started was to fly with 50% fuel, and drop tank. Once engaged in a fight, get rid of the drop tank. 109s with a full fuel load can be a bit unstable sometimes. As you get better, you will learn to cope with a higher weight due to fuel.
I set all my guns to 650yds in the 109s. I tried the 225 - 275 range before, and it didnt work for me. Keep in mind that what works for someone, may not work for you when it comes to gunnery and ranging. That aspect of the game is very dependent on the individual.
My game handle is Emu. Look me up. What is your game handle?
