Gutter overhang

[Diyisfun]

I want to put guttering on one side of my summer house.
The roof is 4m including an overhang of 70cm, so if my first fix is 70cm in, will the gutter support itself. I don't fancy the idea of fixing a batten.
Any tips appreciated.

No it won't over time hot summer days will make it sag.
Can you not drill a small hole in the end and tie it up with some copper wire.
