Dunno about advantages but as mentioned above the Mooney had a similar system. I noticed one parked at Denham once with the elevator trim presumably wound nose up - the fin was leaning forward a little and I thought it must have been damaged - hadn't realised the whole tail unit moved.

Ah missed that bit about the Mooney. That would explain the strange looking upright tail-fin. Ta for the info!

Nigel Mansell operated Jetstar N500NM (later carried VR-CNM) between 1993-1995. This aircraft, c/n 5229, is now preserved at the Pacific Coast Air Museum, Santa Rosa CA.

I already mentioned that.

I don't know of any Arafat connection but he did fly on another JetStar, 7T-VHP, later registered HB-JGK. This was stored at Geneva for some years before being broken up, the fuselage ending up at Kemble.

N971AS, based in Shannon for many years. 1st biz jet I ever set foot in (working but not flying). Impressive looking aircraft.

It's not correct: there is some commonality with the F-100.

G'day Treaders!
Which Mystere fighter? I went with the Super Mystere B2 below.
I don't see the same basic wing shape.
Even the wing specs in Jane's are very different.

I was thinking Mystere IV, which is the variant I'm most familiar with - quite a few scattered around the UK - one would think that if the Mystere 20 and Sabreliner shared names with their manufacturer's fighter products that there would be some common design elements and with the wing being a fundamental part of the aerodynamics...

The supersonic Super Mystère had a very different wing from its subsonic predecessors, as one might expect.

I'm still not clear on the moving fin of the Jetstar. Does the whole fin turn atound a vertical axis to function as a huge rudder? What does the construction look like, has anybody a drawing or picture of this intriguing characteristic? Thanks for any info.

I get the impression that the Jetstar's fin can be rotated in the fore and aft axis to adjust the angle of incidence of the tailplane which is attached to the fin. The rudder and elevator appear to be conventional.

I could be completely wrong, and very happy to be corrected.

Was fortunate enough to 'work' JetStars and Sabreliners - in their mil VC-140 and T-39 guises - into/out of RAF Northolt on many occasions in the mid-70s. As 32 Sqn operated 2 x HS-125-600s, the noise issue wasn't considered an embarrassment in comparison!

Wrt Dassault Falcons, yes the wing was the same as the Mystere's and was a primary reason that Cobham (now Draken) adopted the type for it's ECM training role as the hard points and necessary wiring runs were able to be used and enabled various pods to be fitted underwing 'relatively' easily.

The Pitch Trim Actuator (56) pushes/pulls on the front spar of the Vert Stab which pivots the v stab fore/aft around rear spar attachment (57) and therefore inreases/decreases the tailplane/horiz stab angle of incidence.

The Paris Jet was closest to some military donor (Fouga Magister) it seems.

Less hair

I think the little Paris was perhaps the loudest ever per Kg aircraft built .Aside from the Magisters buttefly tail it was very simialr to the frencjh trainer in many ways .

The Paris was based on the MS Fleuret which competed with the Magister for the FrAF jet trainer order.
