Hi, Just wanted to post that I've created a plugin development kit for XPlane. It's to help develop plugins for XPlane quicker and easier than the XPLM SDK If you are a C# or Java programmer you already know a lot of C++. Give it try. Getting started guide can be found here :http://www.sandorlabs.com/wingman/tiki-index.php?page=GS_GUIDE Complete development kit including the cross compiler environment can be downloaded from http://www.sandorlabs.com/wingman Thanks and ask if you have any questions or issues! Cheers, John
