#43 - Part 2 - Mini Quad Frame Build - Fusion 360 and CNC

This is Part 2 of 2 videos detailing the process for creating a carbon fiber mini quad frame (Drone, quadcopter, UAV, bla bla bla...) The full process covers, composite layup (Making the carbon plate), designing (reverse engineering) the frame in Fusion 360 (CAD), creating the toolpaths for cutting the parts (CAM), cutting the parts on the CNC mill, and sanding and polishing. The wiring and electronics assembly will be another video. The main frame is 5mm thick. Basic carbon fiber stack up is: 2 plies 6oz plain weave carbon fiber 4 plies 22ox quad-axial carbon fiber 2 plies 6oz plain weave carbon fiber The quad-axial used through the center is much heavier and with the varying ply directions making for a more rigid panel in all directions. I also add one ply top and bottom of 3/4oz fiberglass to act as a barrier between the carbon and any other metal components (I forgot to add this on the compression mold plate). Carbon fiber is very conductive so this barrier helps alleviate any potential short circuits from electronics touching the frame. Carbon also is corrosive when placed against many other metals (like aluminum) so this helps with that as well. Anodized parts will mitigate this issue but it's an easy addition that avoids many potential electrical issues down the road. I also added about a 2mm or more radius to the frame edges. I feel this might help with aerodynamics a bit. The arm width is a few millimeters smaller than the original which should also help with drag. The stiffness is comparable to the original, due to the increase plate thickness (5mm instead of 4mm). The frame dimensions are: 5" props 220mm motor to motor Follow my daily bs on Instagram   / dotdissonance
