I've been using iControlDCS for a few weeks now, and the biggest help for me has been the CDU export. I already had the Cougar MFDs with UM80 screens behind them, along with the Aimsworth F16 ICP that I had programmed with DCS functions, but I am very happy with the CDU.
I'll post something in Pit Builders later, but I have a 22" touchscreen coming today that I'm going to install as a front panel in my cockpit to use Helios with. Cap Loz has an impressive setup modeling the entire A-10C cockpit on one 1080p touchscreen.
