That was very helpful i have a X52 as well and found that settings after you said it, It makes controlling the collective much easier, help the bit with learning the landing, the problem i have with landing is not always able to land softly and causes dmg to my ENG. Just before before landing going in really slow the heli starts to glide backwards or forward too fast, or maybe because i am close to ground and feels that way, so i try to compensate or rush the landing. Otherwise once in the air i can fly just fine.
