Hello and welcome on the dark side!
Don't worry about "knowing not much".
I guess, most of is started with only a few knowledge.
First, you should make yourself a plan - Planning your first steps, what you want to build first, etc.
It is s lot easier, if you devide your pit into "smaller" parts - and fully concentrate in their building. Otherwise You will be overwhelmed with Information...
As example: If you decide to build the AcesII, just concentrate in this.
Collect every information about the seat, start collecting parts for it, and so on. Avoid to do many different things at the same time (like Seat, hull and Panels or complex things like DED). You will so other things later.
Once you completed the seat, start your next project, like the hull for example. This will help you a lot in using your Time for learning effectively!
You will find a lot of Support here -
and most Information are avaiable in these forums.
Try to read as much as possible here and you will
find the answer to your questions.
Building, learning and getting the neccessary Informations is a time consuming task...
Have fun and happy building!
