Six lengths of stripwood transformed by the addition of a tile-backer centre-section and what's left of the uPVC skirting used as skis; these are more flexible than the wood on the water-borne prototype, as this airborne version is ideally a little lighter.
Accordingly it features 18mm square-section booms as against 21mm beside those lighter skis, and as a result this chassis weighs in at 10.50 pounds instead of 13.00.
I've gone for black in this case as it's what you'd expect of an experimental quad, in view of the fact the pusher-props and motors at the rear will be omitted for testing. I also had a leftover can of matt black, though it expired long before it was empty ~ something old cans of paint are prone to do and generally when hardware stores are closed, just to piss you off a little more.
I've one more centre-section to dispose of that will feature vectoring rear props, so that it needs only four motors in total. It will though be destined for a museum of our choosing rather than be developed at this stage, as separate lift and cruise motors are easier to implement.
These need neither actuator nor flight-controller, as lift-props sub for collective and pushers an element of conventional cyclic in driving things forward.
Ed. the post's title stems from the fact it is (a) black and (b) Sunday.
