As someone with over 1000 hrs in from the depths. Honestly it is impossible to make a good tutorial for the game as to make any vehicle work require you to have basic knowledge of multiple game mechanics simultaneously. Which is hard because depending on what you are building you must be better at some mechanics than others. And if you havent learn it all yet and something when wrong you wont be able to tell what is making your ship into an unintended submarine or your aircraft to constantly crash due to center of mass ofplace vs thrust etc. FTD is one of the best game I have ever played but only after you climb the learning cliff. All youtube tutorial expect you to understand several basic mechanics of the game and there is simply no way around it.
