The signs explain everything, comment if you have any questions and I will reply to your comment with an answer and add it to a Q&A list here on the top.
Hopefully I helped you to understand how to build your own flying machines, please diamond if I did!
I will update this guide sometimes and upload more compacted parts, and the most important - new parts that solve problems that no one solved yet. The more problems I solve is the more complicated and advanced machines become possible to build! Please let me know if you found a solution to one (or more) of the problems about flying technology.
