I'm getting better with the various 109Gx planes - usually the 109G2 or 109G10. The weaknesses seem to be the "compression" that occurs at high speed, and lacklustre elevator response at any speed (makes getting guns solution difficult). So I focus on its strengths: Excellent climb rate and E retention in zooms. These traits make it a great stealth aircraft - fly at speed, and when a bogie zooms up to rebounce his quarry, the 109Gx can follow him up and catch him at or near the top of his zoom.
Most of my kills come like that - an example film is attached. (I had to clip the film to the bare minimum to make it fit on the BBS)
As a 1-v-1 plane, it's not so good. I had two excellent encounters with TAK in his 190D9 the other day, and whereas the 109G10 was able to maintain an alt advantage, and catch up to the Dora, there was no way for me to follow it in a hard break turn. The Dora is faster, and I was having to go flat out to catch it, so the elevator was unresponsive to say the least at the moment the Dora made its break turn. All I could do was zoom up, then give chase once again. I did try anticipating the break turn, and got quite close, but still not enough elev. authority to finish the job.
I'm not asking for advice here. That is always forthcoming in threads like this.

What I want instead is your 109Gx films like the one I have attached here. I see some of you getting 6,7 - even 10 kills in a sortie. I would like to see how you did it. I never have enough ammo for that many kills, even with the gondolas. I've seen CRESCENT get 7 - and mention that because he's the target in my 109G2 film.
Send me your films via email.
