All the motors and ESCs are going back in their homes on this next build. I believe this is version 3 build now.  Instead of the larger coast guard approved LEDs we have downsized them to LEDs that bold directly to the bottom of the motors. These should save us a ounce or two and have lower power consumption. I should have weighted the new LEDs and compared them, but I forgot in once I was in the groove of assembling the motors and running wires through to new locations to make the build much cleaner.
