Yeah, there’s tons of plans out there for DIY helicopters you can get from the hobby aviation community. Usually the sticking point is making the rotor blades themselves, but I’ve seen some people get off the ground with carbon-fibre laminate blades. Not sure I’d trust them personally but it does work.







It super does though the specific characteristics vary depending on where it was extracted (iirc crude from the canadian oil sands is borderline explosive)
