What are the parts of 8 motorized aircraft. What materials are used?
Are you looking for a specific advice or do you need a list of general things?
not important. But something special is better.
What are you planning to do with your Drone and how big should it be?
You will need:
RX and TX
plus extras (e.g. FPV, GPS)
Also I an answer to your question will require a book to answer as there are alot of things to consider.
I suggest you start reading this - https://blog.dronetrest.com/beginners-guide-to-fpv/
And better yet, get a book that will help explain everything
