Very cool! How long did it take to print? Im gonna try and build something like this aswell in a couple of months :D

about 4h. CF printing is very slow

wow! that's amazing! keep up the good work mate!

Looks really nice! How does the ColorFabb hold up in crashes?

afernan Jan 23, 2019

Thanks!.
Not broken yet (I´ve flown many batteries already with a lot of crashes). The image above showing a crash was with PLA material much more fragile.
This material has a hight stregth (79MPa) and its very resilient. After printing you can apply a "post curing" for gaining 30% of strength and stiffness with same mass.
It´s a bit difficult to print and hot-end eating due the Carbon Fiber filaments...but you get a nice result!
I´m very proud of this machine.

My goal here was to build a high quality 6S racer at a reasonable price. I'd..

Apr 17, 2019

This is the 4th installment to my popular "Wizard Killer" series, and is based on the popular Wizard X220HV 6S.
