Sorry for the framedrops

So, starting the engine on this one is a bit finicky
First hit AG1, then throttle up to about 10%
Make sure that the pistons are spinning clockwise when you look from the front, same goes for all of them (it can go the other way too, just make sure they all turn in the same direction)
Deactivate AG1, keep the throttle up, Activate AG2, make sure they all spin in the same direction as AG1. Same goes for AG3 and AG4.
Once they're all up and running, and have them all activated, you can throttle up slowly to either 90% or 100% (depending on how much you want the engine to randomly blow up). Once the prop is up to speed, either VTOL slider up or down, depending on the rotation, and once again, dont go full up or down or you'll strain the engine making it go boom.

Hope this isnt too complicated :D
Also if you want the version thats a bit faster, go check the predecessor, that one's lighter and faster and drops its gear with AG5, i just made this one here a bit prettier for y'all.

Also, if you successfully manage to isolate the engine, you're free to use it
