Nice job ! 

Do you have an idea of the weight of the empty frame ?

Thanks :)

as far as I remember pvc parts weight was about 900-1000gr (without screws and glue)

Great use of PVC

Have you considered lightening holes in the top and bottom of pvc arms?

Hole in the middle of the aluminum motor plates both to reduce weight and provide airflow through motors (okay I see in the part photos you do have a hole).

That central hub looks like it is built like a tank, plenty strong.

What glue did you use?

Thanks :)

yep, I was considering to make holes but it's require some strength tests, pvc is quite "soft" and also it's could add some vibrations.

To glue parts I used epoxy for PVC but before using it I also add some roughness

This is the glue I used

I was also thinking that you can still replace the PVC tubes by carbon tubes if you need to gain weight.

Motor mount and hub are great in PVC :)
