.... the big mystery as to why ehattons did not order any Martlets???????

 

I agree 100%.. there's a few other new releases missing, however the Martlet does not seem to be available for pre-order at Hattons...

By the way, I not long received an email to say that the JP's have arrived at Hattons and that my four are either on the long journey or soon to be.

The T.4 had a larger pitot tube bracket under the port wing compared to the T.3. source Air Britains  Percival Aircraft  by David Gearing.

The T.4 intakes seem to be enlarged versions (T.5 size?) of those on the T.3s, does that sound right?

 

Is this true?  Were the intakes really of a different size?  There's ways of getting more out of an engine without needing to increase the size of the intakes.

I think the JP4 had Mk 5 elevators but that the basic tailplane is the same shape. Is there a difference in tailpipe shape between Mks 3, 4 and 5?

 

Good question and something I'd like to know the answer to.

Pictures!!!  Or at least links would be helpful.

Having contacted them yesterday and them saying they'd not received anything from Airfix I suddenly get an e-mail telling me my 5 are on their way

 

Anyway, talking of links, these may prove useful...

Some food for thought and research opportunities there!

 

Wez - just getting used to the new website (I'm sure it'll make sense to me eventually)

[71chally]

Wez, think you took me out of context there, we were talking about the two small intakes on top of the T.4 fuselage, from photos they seem to exist on T.3s aswel, but much smaller

James,

 

Apologies, you're correct, I totally misunderstood

We need this in 1/48.

Happily the Jet Provosts have already hit the shelves here in Australia and I've picked one up to backdate to a A99-1 Jet Provost T2, the only airframe operated by the RAAF.

 

Interestingly enough, one of our club members once owned this aircraft

 

Cheers

A couple of sources quote G-APVF/XN117 as having been A99-02 e.g.

I'll get me one too for sure, as soon as they're out here in Germany. And i'll go on waiting for one in 1:48th scale - just like I did with my belived Gnat!

P.S. Now I am hoping for a Chipmunk and a piston powered Percival Provost in "both" scales.

Well a parcel of 5 kits arrived just before I set off for the weekend so I was compelled to bring one away with me for a looksee! What a lovely kit! Straight to the top of the build pile!

 

Nice to see a credit to John Adams and the FAA Museum (oh the irony  - kind of metally like silvery and goldy)

[Selwyn]

As an aside , does anyone do a 1/72 kit of a long legged F1 JP?

Many years ago Maintrack Models did a resin kit in their Protojets range. One piece fuselage and so not so easy to detail the cockpit and white metal undercarriage, which it really needs. I have not seen one in a long while. Whirlybird models seem to have acquired all the Maintrack moulds, so they might re do it at some time. It was one of the early resin kits, not up to SBS and CMK standards, but not bad. The one in my stash is coming out to go with my Airfix JP3. The JP3 decal sheet is pretty good.  I reckon it will take as long to put them on as to build the kit id you pick the 2FTS option as I will be doing (another aircraft based in my home county, despite what the instructions say)

So do we have a definitive list of the differences between a T.3 and T.4?  Every website I've looked at only mention the engine but on this site we've had mention of intakes, pitots and elevators, so were there genuine differences that can be backed up with photos?

[71chally]

The pair of intakes I mention are on the top decking to the rear of the engine access doors.

The T.3 ones are quite shallow,

The T.4 ones are much more pronounced in height, like those on the T.5 I would say,

Note both variants have the shallow inlets just aft of the top ones, and lower down the fuselage.

In answer to differeces between T.3 and T.4 did the T.3 not have those wing leading edge root fillets as per original Airfix kit of the 1950's/60's? Or were these only on the very first few early Mk. 3??

[71chally]

The T.1 style inboard leading edge was on the prototype T.3 XM346, which was later modified to the production standard straight leading edge.

Unsure if fitted to other early T.3s, would make a nice and different mod to a standard build.

 

That's got me thinking, can one of the few T.2s be easily modelled from a T.3? G-AOHD would make a nice subject.

Because of that, I converted an old Airfix T3 kit to a T.1 using a Matchbox piston Provost's canopy, stretched sprue undercarriage legs and scratch-built. doors. Finished it as a CFS Jet Provost Aerobatic Team aircraft of 1958.

I think those shallow inlets aft and below the top Inlet may actually be handholds let into the engine doors - I think to give a hand hold to help the climb up onto the wing walkway (there is some rubber cushioning at the back of the depression) - but I stand ready to be corrected

 

I took a few photos when i was building a 3A and a 5 and here's a couple of the JP 5 at Hendon:

 

 

 

And of the JP 3A at Newark:

 

 

 

I also took some of the different elevator horns:

 

JP5:

 

JP3A:

 

However I'm afraid that I don't know if the elevator modification came in with the JP 4 or at some other time or whether it was an in-service mod and retrofitted or whatever.....

You're absolutely correct Steve, they are handholds to assist one to clamber onto the walkway at the wing root.

 

If I get chance I'll pop down to our museum the morrow and take a look at our JP3.

I've been checking my photo's and all of the JP5As have the later style elevator horn.

 

Additionally what photo's I do have of the JP4 also show this style horn.

 

I think it's safe to suggest that the modified horn came in with the introduction of the JP4 and was not an 'In Service Mod'.

 

I would warrant that it was something to do with elevator flutter given that both the JP4 and JP5 could achieve 400 kts.

[71chally]

Thanks for the handhold correction.

 

Can someone illustrate the suggested elevator difference the 3 & 4?

[Ascoteer]

Chally,

 

From the photo's I have the JP3 has a full chord elevator horn balance whereas the JP4 has the truncated type (same as the JP5A one illustrated above).

[71chally]

Ah, got you now.  That shouldn't be too hard to correct/make up.

[Ascoteer]

I popped down to the Museum this afternoon and can confirm that our JP3 has the full chord horn balance. Ignore the spurious paint scheme, XM402 is a JP3 that was never modified to JP3A status. She served with 2FTS Syerston and then 6 FTS Acklington, before being struck off charge in 1969 and going to Newton, then later Halton, as a Ground Instructional airframe. As such she should be in the silver/dayglo orange scheme (don't ask!):

 

 

 

 

I also took a few shots of the engine bay doors:
