So, got some news:
somewhere my math went terribly wrong, after redoing it the bot was about 1.6kg too heavy.
Switched back to 4mm titanium for top and bottom plate (guess i shouldn't ram the wedge into spinners now) and made the weapon only 20mm thick.

now it's almost okay again, still... unsure if i could make the spokes a bit thinner without risking to break them or any other way to save weight or optimize the disc design, so i'm sharing it with you.

Hope this works...

Balance seems good, it's just still very heavy and looking quiet massive on the inside.


Or do you guys see any other part in my sketches where i could save some weight?

it already seems to be kinda fragil.
