Make the use of propellers/rotors easier and more stable.

When trying to make something propeller/rotor powered right now has major bugs, like you cannot have an adjustable pitch blade on a motor, if you do stretch it will stretch out and break majorly.
Somehow either make propellers more stable to make, such as making it less volatile, more thrust produced without having to jank the XML, or making a procedural part like you can do so in SP, but the blade parts maybe being separate?

edit: Okay so there's already something very similar to this suggestion, and really thinking about it, I don't think they will want to add propellers to a space game, but hey might as well leave this here and see what happens.
