I have a little time on my hands right now so I will do some testing.
So I took the MD 500 for a quick spin and there are some things I don't like. The first thing I noticed was that I need almost NO pedal input during takeoff/hover/landing (All you need are some tiny corrections and as soon as you fly 30-40knots you don't need pedals at all). I quite like the way it is in 1.03 (although I like the increased sensitivity in this beta). It would be great to hear a real pilot on that matter. Second thing I noticed was that, like OMAC, I had the feeling to get 'sucked' into the ground when I landed. So maybe increase the groundeffect a little bit.
Having flown a little more I can say this sounds more negative than it is. I reduced the sensitivity for the z-axis on my joystick and it is better. I still have the feeling that a little bit more noticable torque effect would be great. A bit like it is on the medium Heli at the moment.
What I do like is the increased sensitivity and responsiveness of the controls. I quite like how the Bell 412 handels. You only need minimal (but constant) control input and takeoff/hover/landing feels much better compared to the MD 500 (I really miss the need for pedal input on that model) .
I fly on Expert btw.
