I purchased the Logitech Pro Flight Sys. in June, 2017. Haven't flown yet because I can't get the throttle to respond properly yet. I have followed all the instructions on both the x-plane program and the Saitek site. I have calibrated all the equipment many times to no avail. ( I am using a 2.0 power usb hub that is recommended for the Saitek add-ons. ) In fact, I can't even get the flaps to work either. They are always at FULL. So, as a result, hard to get off the ground. When I advance the throttle, on the monitor, you can watch the throttle stutter, if you will, as it tries to reach FULL (which it never does) 50% is the best it gets IN ALL PLANES. As I throttle back to stop the engine, on screen, it stutters and stays where it is, 50%. Calibrate again. Nothing. In fact, I have disconnected the yoke and throttle sys from the mix and only used the key pad. F1 and F2 does't work either, nor do the flaps. And yes, I have started the program many, many times after making changes. EVERY THING else works as it should, as far as I can tell.
Then I decided to delete and reinstall x-plane. I bought x-plane on Steam. After x-plane was re-installed, there was no change. Except now the C172 is black in the icon, (now what ?) Every thing else mentioned above remained the same.
Any Ideas? I need to fly. I have a new computer with tons of space and running three monitors.
