I know doubleposting is bad, but I do it anyway.
So I have been flying around in the dev build with the Littlebird, the Mohawk, the Ghosthawk and the Blackfoot and so far I have noticed the following.
- It feels like your helis have actually more mass
- This made me feel like I had a bit more control over the helis, especially on lower speed. I had less unwanted drifting on lower speeds
- Yaw seems to work better now, so you can use it more to control your heli.
- I think when you are hovering close to the ground you now have a pocket of air below you that can give you a bit of updrift. I cant really confirm this but it felt like this.

So far I like it.
DISREGARD!
Nearly half of the new options were turned off in the game settings, so I have to test it with all of them being enabled.
