Heli's work but not planes in Alpha81

[RadBoyGo]

I've just been playing with FMS alpha8.1 and have discovered that on my computer (p4 2533, ATI Radeon9700pro) the helicopters work fine and are much better than previously.
However, all planes function in super slowmotion and are impossible to use.

One thing about helicopters, they appear to accelerate to slow towards the ground when cutting throttle or reversing the thrust. Both my helicopter tend to rocket towards to ground and disintegrate when the collector is reversed.

Other wise I relly like the new version. Hovering with wind and gusts is very good. Translational is missing but I dont know if the gravity thing is more important.

thanks for sharing such a nice piece of software
