You can find the WIP silkopter code here:
It’s quite a lot of code as it includes a 3d engine used in the ground station.
It depends on boost, freetype2 and bullet physics for the simulator.
I use QTCreator on Ubuntu 14.04 for development but the code should work just fine on windows as 6 months ago I used to develop in Visual Studio 2013.
The code is published under GPL.
