Default Can you give me some tips on how to properly fly this aircraft?

Ever since I've got it this aircraft feels extremely sensitive on the pitch axis in particular. I am trying to keep it as traight as I can either with the joystick or with triming yet the same thing happens again and again the nose goes up and down I just can't keep it stable.
Also its the only module that distracts me. When I am flying it I just can not establish the horizon on my mind and it feels like the aircraft is sliping.
Any advice would be great.

You might want to adjust your curves to those values suggested in the screenshot below:

Absolutely no problem to do what I want with this plane, I fly it 99% of the time. My curves are so so different than picture below, it would be impossible to fly Albatros with them for me, my wingmen too. Have you other module? If yes no problem with them ?

yea i've got a ton of modules. I even fly ww2 for christ's shake. I will check tomorow the proposed curves and see how it goes

I have found that getting level flight is a careful balance of trim and power. Don't forget to adjust the throttle when trimming. I can usually get it balanced well enough to fly the plane with slight adjustments on the trim switch alone.

I use similar curves on pitch and roll axes on all my DCS aircraft. Just my preference. Seems easier to fly steady and in formation like that. Others insist, "Oh, no-no-no, you must keep linear. Using a curve is a crutch". I ignore them. I only add a curve. About 17 to 25 in both pitch and roll. Sometimes I put a slight curve on wheel brake response, too. Whatever feels right to me for the aircraft. In the image here, the pitch axis appears 'truncated'. I wouldn't do that. I'd keep it full throw capable. Just the response curve to where near center, the response is less. I think this is making up for our "short" joysticks with spring resistance. I think most real aircraft have longer sticks that are mechanically connected to a hydraulic input system or cables and/or push rods and levers.

Like doodenkoff said, here, a balance of trim and power. Often I'll set a desired power setting and chase level flight with the trim, gradually smoothing out to the right trim for the right airspeed for a given power setting. Whether you hold trim and adjust power or hold power and adjust trim, it should eventually dampen out. If you are adjusting both, you're probably chasing it all over the sky. And flying in formation is constant work of fine adjustments.

Also, I think it helps to have something like the Thrustmaster Warthog which uses Hall effect sensors and has no 'flutter' or 'noise'. When I let go of the stick, it always reads a steady 0 on the X and Y axes (or if not zero, a steady, consistent number). Plus it has something like 16,000 points of resolution which seems to allow for very fine control inputs. There may be some other quality joysticks that do this, too. But those that use potentiometers instead of Hall effect are noisy and low resolution...like only 512 or 1024 points of resolution. Then you need to add 'dead' zone to cover the 'noise' of a centered stick (noisy pot). However, if the stick (pot) is noisy at center, it's probably noisy at all other points, too. If you often see flight control surfaces, or the stick, slightly fluttering when you aren't touching it, your stick probably has potentiometers. Real aircraft have approximately infinite points of resolution.

The pitch trim on the L-39C seems maybe slightly too coarse. Might need more points of resolution, or a slower response speed. Then again, the real flight controls of a real aircraft aren't always that "self-zeroing". I had trouble holding altitude in a real Cessna 150, too. While my flight instructor seemed to have "the perfect touch". Just practice and experience. Keep working at it and remember to relax your grip of you are too tense. Hope that helps.

And on pretty much all DCS modules, it seems like once you touch the roll trim, you can never get it back to a perfect center. Always causes you to hold slight control pressure either left or right for the rest of the mission. That's my experience.
