To create the 'stays' that will capture the lower end of what I shall call the connecting rods joining rotorhead and passenger platform, I have used kitchen-cabinet brackets. When you call at the hardware store for these, be sure to ask them for aviation-grade brackets as well as tartan spray-paint and a long weight... and say I sent you.
What I've done here is select a corner-shaped off-cut and used it as a template along with a couple of off-cut tubular sections. Then using a market we will be able to carry the location of the bottom-end of each connecting rod upwards to the same point on the upper side of the box in which the pilot/passenger will be stood. If that makes any sense at all to you, take a lollipop. Everyone else, be assured it will all come out in the wash.
