A quick mock-up to ensure it'll all fit together. 36" cantilevers connected by inch-alloy sections cut down to 750mm to allow for the M6 tube-inserts to accommodate bolts. Either side of the booth are inch-square plastic extrusions taken down to 295mm to suit the same tube-inserts. Although these brace the airframe they are non-structural and serve principally to retain the inch-thick insulation foam that will be used to pack out the voids prior to application of shear-webs top and bottom. These to be identical so that the lower quad can be raised around the box to some extent prior to fitment in order to provide ground clearance for the props. All in all a promising start, and as ever, starting is invariably the hardest part. Well done, Colin.
