Lot of problems with the design.
The cockpit is of course completely out of step with the popular notion of decent all-round view, being both too high at the sills and razorbacked.
On a similar note, the inlets and canards both block rearwards and downwards views while sitting too close to the ground to be out of ground effect
and FOD hazarding conditions (IMO).
Having large endplates on the wing will up your RCS quite a bit and lead to some directional and roll inertia problems in some flight conditions.
Similarly, putting both tails AND landinggear outboard is structurally unwise for weight and strain on the wing roots.
I would also state that the layout seems likely to restrict any underwing ordnance to just one pylon per side, thanks to flow complexities and
clearance factors coming off the inlets, canards and tiplets. It may also prove to be difficult loading the thing as you would have to either raise
the flaps and bring the Jammer in from behind. Or turn it almost 90` getting behind the canards.
In general, given the almost total failure of ejector lift under operational conditions; I would instead go to a high, raised, fuselage, putting the
inlet above and behind the cockpit ala F-107 while keeping a short case turbine (F124/125) that could make the most of flap blowing -ahead of- the TEF
surfaces. Also adding either a secondary lift engine or a gas/shaft driven lift fan system in a large LEX/Chine type surround on the fuselage aft the
The cockpit itself would have to be moved forward and the tails would have to come in to the centerline so that I could increase the wingspan.
The 'nice thing' being that you could have controlled (80 knots, 400ft) ESTOL without the bulk of the JSF's internal carriage requirements in a
decent CAS jet with a large centerline payload option and at least 2 wing pylons per side.
VTOL/STOVL is, IMO, always going to be a fight against plumbing vs. package size that will never come out right until they invent some kind of gravity
field generator or _very_ powerful, small, rocket packages.
