Hi Andre,
mistakes are there to be made, but learn from the mistakes of others, you do not live long enough to commit them all
There is a forum for analyzing errors, reconciling them with their own experiences, and helping to eliminate them. Impossible things we do here immediately, only miracles, miracles take a little longer
Joking aside. If Mobiflight can do something, many bring in their knowledge to help others. There are no stupid questions, just stupid answers.
Many tips you can get yourself here in the forum, work through the tutorials and thus gain their own experience. You'll see how easy it is to handle Mobiflight and how quickly you can get things done.
Before you start spending money, you should create a plan for yourself that describes where you want to go. Gray is all theory, but it does not work without it. But you can also help with the planning here, so that you can get a very good idea of how you can realize your project. That makes sense and saves money.
Before your planning just let us know what you plan to do. This starts with the simulation, continues on the desired aircraft (not every one is suitable for cockpit construction), basic technical knowledge (not at all, beginners, advanced or professional), construction projects.
If you've ever browsed here in the forum, you will have found that there are a lot of users who have built a lot. The results are often illustrated. I think that can be inspiring.
Let's go, we are curious.
