I was thinking that it would be cool if the devs expanded on the tutorials for SP, to include tutorials on how to build helicopters.
These tutorials can include the basics of helicopter construction, the functions of the heli parts, as well as some tips to consider when building, such as:

1) The power ratios for the main rotor and tail rotor and linkage speeds
2) Engine CoM offsets
3) How to build with different rotor configurations (Conventional, Tandem, Coaxial, Intermeshing, etc)

Also some flight tutorials for said helicopters would be nice, to further explain the principles of helicopter flight.

I feel that it would make things a lot simpler for the newcomers.

Feel free to leave your thoughts in the comments.
