What most inspires about the design is undoubtably the enclosure and flight-deck we have, that stems itself from a prolonged evolution of the ideal means for short-range personal air vehicles of this kind. Aside from this however the key to the effectiveness and practicality of the outline is undoubtably the division of lift between an upper and lower drone, each of which can be separated from that enclosure for either transport or storage; and each of which can be addressed separately with a view to redundancy.
As we've to rebuild the airframe to some extent before testing its constituent drones, then crisis can be turned opportunity by examining whether alternative arrangements of airframe might suit equally well. This is one we've flown before, albeit terminated at around waist height for an operator stood within it. At the time, pitching the upper drone in the overhead did not look structurally feasible, but after countless variations it would appear that in fact it is.
Nothing in the sketch above has not been assembled before, and merely rearranges its constituent parts to suit present objectives. It's not rocket science and reading about the struggles of private individuals to put actual rockets and miniature satellites into orbit, the one thing to take away from such endeavours is the time that taken to turn vision into reality. Almost without exception, the current crop of billionaires took not years to elevate themselves into orbit (which still eludes some of them), but decades.
The outline above will be constructed at half scale to suit the current mannekin; seen below in platform it features a foot-wide phone-booth within a three-feet square that pitches the propellers at a diagonal distance of 4.25 feet or 1.30 metres. It would thus feet the dimensional strictures of GoFly's Challenge only with the propellers removed. Nonetheless such challenges as these, like the X-prize, set the ball rolling in pursuit of products that we'd like to see brought to life.
