This news is several months old, but Gadroc has released the source code for his Helios touchscreen virtual cockpit software.
I've been tinkering with it, and it has some really nice features. And I know there are others out there using it for BMS and DCS.
I'm no coder/programmer, but someone else might be able to help improve it.

It was primarily developed for BMS and DCS. But I've been using for other games, using a windows tablet as a touchscreen cockpit/controls (but limited to only sending keyboard keystrokes over the home network). It would be cool to see it's capabilities expanded to better support network inputs for other games like IL2 1946, Cliffs of Dover, or even ARMA3 if possible.

I'm not affiliated with Gadroc or his software. I just have a selfish interest in seeing it live on and progress into something more badass.

I've experimented with it and Elite and so far, it has worked! Pity I don't really need it for Elite.

I love Helios and don't know where my multi monitor set up would be without it. Kudos to Gadroc for making it and for him releasing the code so that others can improve on it.

Has anyone been able to fix the Radio use of HELIOS for DCS. The switches quit working correctly back in like 2014 sometime.
