(in regards to OT)
to be honest - didn´t listen to commentary, but imho I spot few design flaws:
- retractable lift-only front fans: Too much dead weight, too much space lost
- multiple slots at front canard? too much drag, less lift
- I am no aerodynamicist, but the design overall seems more to please an investors eye than to maximize lift from every bit of surface.
- from my short experience Dysons bladeless ventilators produce impressive volume of moving air, but at an expense of greater wattage than conventional fans. You need to beat internal friction of massive volume of air pushed through relatively narrow tube.
I hope I am wrong, but it seems like Paul Moller offspring to me. With todays overpowered modell airplane motors its easy to fly any EPS structure, and too easy to produce appealing animation. Investor trap.
