Here is the newest 3D design for the drone arms. We have both 8 degree and 5 degree dihedral axis versions with " Hackaday 2020" on one side and "Sky Anchor" on the other. A variation of the Jolly Wrencher logo adorns the space between the text. After physical modifications I found that I was able to reduce the weight to the OEM 1.8 ounces and now with the newest variation of the design it could be even lighter, yet still maintain strength and more rigidity than all the previous versions. The first two arms are on the printers now with an estimated print time of 12.5 hours. I will update everyone once I have the new ones off the print bed. This is not where we will stop to reduce weight on the air frame. We still need to lighten the top and bottom plates of which currently we have 4. The spacers between plates are just rectangular and these could be lightened a couple ounces between all of them. Also the entire top level that is vibration isolated will be removed in favor of only vibration isolating the Pixhawk itself. The new power supplies will be 3/4 the size of the old ones, so we will likely design a newer and lighter power supply frame. The current landing gear will likely be removed in favor of a wider landing gear that doubles as a mount for 360 degree mounting for 8 of the 5G long range access points.
