Turns out it wasn't the 300th post, but this is. Here's the inspiration from the original patent filed a few years back, and as you can see all that I have done is to join the dots in a much sturdier frame altogether. The logic stands, however, in that the eight motors can actually be addressed as a 'virtual' quadcopter.
(Alternatively those motors at the corners can be used for steering alone, whilst those between might address lift alone, so that the conventional cyclic, collective and yaw controls associated with helicopters might still be incorporated.)
Addressed as a quad, each pair of motors would rotate in the same direction, which is not what you would expect of an octo. Life's full of surprises, isn't it?
Whether these efforts come to fruition ~ or whether I return to the double-decked design currently simmering on the back-burner ~ is up to fate itself.
