Here's the box secured to the lower quad. The cantilevers are terminated at three-way connectors that provide for a motor pylon at the corners, with the total weight of the payload carried through the airframe at rest (allowing for a higher drone altogether). Happily though the mannekin is split into halves and can be flown like Douglas Bader with legs either on or off... else absented altogether, which makes for flexibility at the flight-testing stage. Those undercarriage legs incidentally can be fitted with skids, but I can't be bothered buying any more plastic tubing for now.
Target weight suggested by the gurus back at the lab was twenty kilos, and what you see here weighs just seven. I could have added a back to the 'phone-box' in order to stiffen things further, but we'll keep that one up our sleeve at present. As it is, ingress might be from any side of the vehicle, and that step into the foot-well is scaled at the ten-inch (25cm) mark, which is as good as my old knees get at this stage of the game.
