Good morning, good afternoon, good night depending on where you live, I'm about to start developing a Eurocopter EC725, however, I have a problem building the helicopter itself...

I need tips on how to make it stable and especially on how to make an accurate fuselage that really looks like a helicopter if you know someone who knew how to make helicopters Don't forget to tag it... Because I have no idea how or where to start, any tips are welcome
