Nobody is going to make fun of you if you ask questions about stuff here. If they did, they'd probably get banned because this is supposed to be (and is) a very friendly community. In fact, even though I like aeroplane sims too and write reviews for other websites about that and other stuff, I think it's fair to say that I spend more time on this forum than any other, simply because it is so friendly and fun.
Anyone who considers themselves knowledgeable about a subject that would mock someone for asking a question about stuff is beneath contempt as far as I'm concerned, and I'd say the vast majority of people on Subsim would probably think that too. Both myself, and I daresay others, would be more than happy to answer any questions you might have (if we can), as there are few things people like doing more than talking about a subject they are interested in! So go ahead, ask away if you have any questions.
