Thanx for all suggestion folks! I just couldn´t understand why I couldn´t land the damn thing while I has been flying this sim for nearly 2 years! (I also plays a lot of Lock On and some MSF X so I am very familiar with flying on the comp!). So, today I watched a replay of a track. I came in on an almost perfect glidepath and touched the ground with my plane almost perfectly and suddenly once I touched the runway with the wheels, I flipped over. This can´t be right I thinked....something is very wrong! Yep! Something was indeed very wrong. I have bought a new mouse with a PS2 connection to free up USB connections. And guess what, my Saitek Quadrant suddenly had wrong ID on the prop pitch. I discovered my proppitch was brake! And the leveler was on max! I did not discovered this in the 109 because I can´t use proppitch in this aircraft because it´s on auto!
So, I just attaced the brake to rudderpedals and sat proppitch correctly to the Saitek Quadrant and perfect landings! I am so happy!

I thought I had just lost it, but now I know 2 years practise plays off!
