Ya ya,
Set up Teamspeak for the SimHQ channel.
Here is a link to (very old) start up procedure. I would guide you through that so you gain an understanding of the controls.
We talk the language of cockpit switches, DMS UP Short, China Hat Forward Long, so you need to know your mappings and it is good to know the key commands, too. Look in the A-10C manual, pages ~88-92 for these switch positions.
Try this link to DCS User Files for A-10C Documents -- there is a key map there. Look on about page 3 of that link for Toby23's document pack.
After a while all this stuff will be old hat...
