Welcome to the forum.
We have many members who are into both SCI-FI and real aerospace. All of which are willing to lend a word of advice (if needed). So if you have any questions, do not be afraid to ask. I am certain that they will be willing to answer them (or at least point you in the right direction.
If you have any models that you have built already, please post them (in a new thread of course). If you are currently working on something, please post a build thread.
Build threads are a GREAT way to show off your skills and techniques, as well as show where you are having problems with a particular part of a build that you need help with.
As for your English, do not worry about it. We have many members from around the world (that have problems with English). If you are having problems, just use google translator.
Once again, welcome aboard and I hope that you enjoy yourself here.
I look forward to seeing your work.
