Before I place my questions and ask for your help, I want to introduce myself.

My name is Dimitris, 36 years old, and for more than a year now I've got involved with Flight Simming. I got so excited that I decided to start building my cockpit, beginning from the fundamentals.
I learned that there are many skillful and informed people in this community, so I believe I am in the right place for guidance and some brainstorming...

I wish you a Merry Christmas.
