Combat trim is fine in 109's; the only time I trim anything manually is at high speeds, when you need to trim to get any kind of elevator authority. Other than that, I leave it on. It requires a certain touch to keep them from flopping around, but once you figure it out, it's not difficult at all. I have absolutely no trouble with snaprolls at all, and I routinely fight with it under 200mph. And you can't say that I'm not well versed in the ways of the 109... I should hit 800 kills in the K4 if I fly tonight.
"Me 109 G:
"It was very advanced and equipped with new, more sophisticated technology. Nicknamed Gustav, the 109G was well armed, but not as light as the early E and F versions. Its more powerful engine meant higher power settings whose initial climb rate sent it soaring to 18700 feet in six minutes, but at low speed the plane was difficult to handle."
