Have a go at it, try to test things out. With your stick, you will have to use the keyboard -- A LOT. Don't blame us for wanting a TM Warthog later on

Might I suggest looking at page 38 of the DCS A-10C QuickStart Guide EN on your /install/Doc folder... that will show you what's mapped to the actual Warthog stick and the relevant keyboard commands. Might be a good idea to print it out too.

Then start tackling the tutorials, and refer to the FAQ and Training sub-forums here on DCS A10 for some newbie-friendly guides.

Good luck!
