So here is the nearly completed build. I built it for 6S and I'm using a Tattu 22,000 mah 25c smart battery. I used 5008 350kv Arris motors, 60 amp Flamecolor ESCs running open source SimonK firmware on a Tarot 680 Pro frame, including servo operated retractable landing gear. I'm using the Tarot ZYX-M flight controller/autopilot with Tarot ZYX-M OSD and a Tarot 3D Metal 3 axis gimbal for Go Pro sessions camera. MY RC is a FrSky Horus X10S Express with dual channel 2.4Ghz & 900Mhz radios. I'm using a very high power AKK receiver with adjustable output between .25 to 3 watt output. For safety I'm in the process of incorporating an infrared lidar unit and millimeter wave radar although I have not yet made those last two modifications. My future upgrades are a Skydroid C20 camera and I would like to upgrade from the separate VTX and receiver hooked up to a display to a more all in one GC Station like the 20km Herelink or Skydroid/SYMI system. It certainly helped that I'm an industrial automation engineer and very used to working with control systems, servos and drives, PLCs etc. I took the pic below yesterday to give my brother some idea how large even a 680 Hexacopter is. I'm glad i didn't try to build a 1000mm or larger multirotor. This project has definitely been a challenge. The 14 inch props are just sitting on the motors and the Antenna/GPS antenna are not attached. As mentioned earlier, it's not quite yet complete. I have bench tested motors, ESCs I've got transmitter and receiver bound to each other and communicating but I'm still working on setting everything up.
