I have been making changes to the MechJeb Autopilot for Kerbal Space Program to help reduce the jitter or twitchyness of the Roll/Yaw/Pitch controls. Comparison video:
The file I have been working on can be found here: MechJebCore.cs - http://pastebin.com/ed6Z4azN If you are interested in checking out my version of MechJeb Autopilot you can get the Plugin DLL here: https://dl.dropbox.com/u/94067015/MuMechLib.zip You can find the original source code here: http://svn.mumech.com/KSP/trunk/ Using Visual Studio, make it a .NET 3.5 solution as the .NET 4.0 solutions cause problems. Mono developers may have similar problems but there are work around on forums. Also if you know how I can get into touch with the developers to see if they would be interested in integrating my changes, that would be much appreciated.
