This is my version of a carbon 250 quad. It’s based on Hammer v 3.0 plans (big thanks!) but I have made some modifications that suit my taste.

The carbon pieces are self milled on 1.1mm carbide tool. 16.200rpm, 0.5mm layer, 210mm/min.


Each arm weights 10.1gr. Thickness 2.91mm. Modified from Hammer arms; removed that suddenly narrowing shape (weak point) and made it “evenly breakable”. They are still 100% compatible with the original Hammer design.



The two identical base body plates weighted 23,8gr each. They are 2mm thick carbon fiber.

Motivational assembly! 100gr total at this point.
