    It looks great. Very good idea! One of my favourite MOCs. I hope you will build more like this.

    Hello again,

    Another question, if I may ;-)
    Looking at the parts list in the final assembly pdf, I see parts not found in the rebrickable inventory.
    Obviously the arduino and the motor shield are missing as those are NO LEGO parts. These are mentioned in the description, so  that is OK.
    But the other parts I miss look like LEGO:
    As an example the blue pneumatics pump and a transparent part on the same pdf page.(last page).are not in the rebrickable inventory. Not even an idea what kind of part that is..
    On the page with most white parts, there are a number of parts that lack a partnumber under the image.
    They look like turbine blades .but I cannot find the part-id anywhere (rebrickable / bricklink).
    Any idea if we can have a complete Rebrickable inventory so I can order my missing parts before I buy the building instructions, please ?

    Thanks and kind regards,
    Bert

    [edit]
    Forget it I did not see the "Turbofan Engine Model Desc.pdf"
    For me too many 3D printed parts, non-LEGO bearings and cable reconfigurations. Beyond my target. Sorry.

    [edit2] Thank you Mike my questions are answered in your reply on my questins below.

    Is there a way you can update the "Features:" portion spelling of the word vains to the correct spelling vanes?  This turbofan engine MOC looks great.  I will buy the instructions, not necessarily to build it but just to appreciate the build techniques in this MOC. Thank You.

    Would you be able to share more info on how the functions works, particularly the FADEC logic. It does look fascinating and something I would like to build, unfortunately the instructions are too expensive for me.

    Awesome! Do you have a video of it by any chance?
