The Fragile One - Forged Carbon Quadcopter Frame (4 inch)

thingiverse

ALL NECESSARY FILES ADDED If you want any more info, please feel free to comment. :) This is a project of forged carbon 4incher quad. Forged carbon is a way to make omnidirectional carbon with just some carbon fibers. The frame is a little bit on the heavy side but its really robust and rigid. If you want to enlighten the frame, you can just push the upper part lower into the form with less fibers. It can get 20g lighter and still flies perfectly for long range. TLDR make threads in every M4 hole on the forms so you can took the final result out, use wax or release agent to prepare the form and fill the holes with threads (or screw there some m4 screws and wax them to protect from resin). Fill the from with resin, short carbon fibers (10-15mm length) (around 70g of fibers to have a spare). It takes around hour to fill it well. Then press it hard with vise or clamps and something to keep the form flat. Wait until the resin is fully hardened and then screw in as many screws as you can and slowly tighten them up to take apart two halves of form. USE PROTECTION GLOVES because the short fibers with resin is really pointy and sharp and everywhere. Then file the excess resin and fibers, drill holes for bottom and topplate and screw it all together with M2 screws. The hole positions will be noticable, because the form has small 2mm points that will make the pattern on the forged carbon. You won't miss it. The 20x20 holes that are for the FC, ESC and VTX are 1,5mm and then threaded with M2 tap. So you can just use M2x20mm screws to fix a flytower.
