Their website says "Flaps down stall speed = 45 kts" ... so they're confident it's a pussy-cat.

I'm sure we have some Spitfire expertise here, such as Danny42C, who could comment on stall characteritics with an elliptical wing.

B/A ratio guesses anyone?

From what I recall, an elliptical wing gives optimum lift distribution with significant benefits with regard to lift dependent drag. Also the effective AoA is constant across the span.

A bit of a bugger to construct though. The efficiency of the Spitfire wing was all very fine, but it meant that the tapered wing Bf 109, though marginally less efficient, could be built far more quickly.

Swift? Not a very happy name for a military aeroplane in its earlier incarnation!

I wouldn't of thought so as it's plastic.

Flew an ex-employer (property/carehome developer) into this very site over 10-years ago. Wasn’t viable then so interesting to see it back on the market. Whilst we concentrated in ‘The North’ (eg RAF Middleton St George Officers’ Mess is now an award-winning carehome )
Maybe it could double as the Solar Panel Controller’s house?

It used to be a very good hotel especially after you had told the Air UK hostesses on a night stop about the ghost who flew his Meteor into the side of it.

….because the Spitfire's elliptical wing was intended to allow (relatively) high Mach numbers
No it wasn't ! High speed (in terms of dynamic pressure as opposed to Mach number) was because the wing had a low thickness/chord ratio.

Elliptical lift distribution offers constant downwash across the span and hence low induced drag.


BEagle is correct
.
...with RTR (redacted thrust reheat)
I know not where you found that strange terminology. The Jaguar had part-throttle reheat (PTR) whereby afterburner would remain lit when the engine was throttled back as far as about 90% rpm. It was selectable by switches just below the canopy rails on the left hand side.

I have 1850 hours on the aeroplane.

Mitchell wanted a fast aeroplane but I dont think he ever thought about Mach numbers

If I was to offer an educated guess I would say the project is funded by govenment research grants and may get as far as flying but will fail to make it into production............ regrettably.
