I will second that.

It's a great feeling when modellers, whose work you admire, post such nice comments. Very grateful.
I have been building up the body and the nose and tail. The fit is excellent. The only problem with the body is it is made up of many parts. Very little will be seen especially as I'll be fitting covers over the intakes and exhausts. Although all these parts fit very well, even a slight error, just a fraction of a millimeter out, and repeat that with the build up of parts and things aren't perfect. So a little fettling and a tiny bit of filler was needed.
It is looking like the Buccs iconic shape. The wings have been razor sawn off as the kit gives folded wings which I have chosen.
Thanks again guys. Happy modelling
Seems boring to have just grey plastic when so many of you are joining in with the race/rally car GB with all that blue, yellow and red plastic and sparkling chrome :smiling::tongue-out3::smiling:

HI Jim your bucc looks good nice to see someone else havein a go at a cut an shut model lik my tomcat as it makes the model so much more intrestin an like miko has done very well done so far an i'll be followin your build

Nothing wrong with a bit of grey plastic, especially when it looks as good as that!
Just out of interest Jim, does the kit show/have the tiny little vortex generators on the upper leading edges of the wings? When working on them in training I always they always drew blood when scrabbling over the wings. (Never got to work on the aircraft after training).
It's coming on a treat, even 'naked' it looks every bit a Bucc!!!

Thanks for your posts :thumb2:
A bit more progress
Front section and rear sections joined to main body. Fit wasn't bad but a little filler needed.
Filled and primed to see if things are ok.
Made up the access ladder. Not perfect but it will be fine.
The folded wing parts are all cleaned up and sorted. Some parts will only be fitted after painting and decalling as the decals go under them.
Simple answer Doug is no.

It does have vortex generators Jim.
Last pic, the left image. It shows the small little triangular ‘things’ along the upper leading edge!
They are the vortex generators. They control the boundary layer of air over the upper wing surface. Basically, the little triangles stop the air in contact with the wing from sliding away sideways and help improve lift!!!
Thank you Doug. I didn't know why they were there or what they were. One of the strengths of the forum is that there are so many knowledgeable people :thumb2:
I don’t have a clue why they called them generators!! All they do is keep the air in line over the wing surface!!!

I think you’re confusing them with wing fences here. A vortex generator makes the air behind turn into a spiral, thereby making it stick to the wing’s surface better.
A wing fence is a much longer structure:

This does prevent the air sliding sideways off the wing, which is dangerous because it can cause the wingtips to stall while the rest of the wing doesn’t.
Because they generate vortices in the air flowing past them?
(source for these three images)
Well the Bucc did have vortex generators, and it was used to control the boundary layer. I just blew the explanation. They would to a degree have the same effect as the wing fence but carry it out on a more subtle way. They would still direct the airflow over the wing as well as keeping the air close to the wing surface. It was some 55 years ago I last did fixed wing theory of flight!!

Great progress jim , its looking mighty fine , cheers tony
Brilliant work going on here, mine has move a place or two up the 'to do' in the raspberry ripplification plan!
Psst!! don't mention the Buccaneer 'blown flaps to increase high energy air and prevent early onset boundary layer separation! or we could be here all over again!
Miko (aerodynamically efficient!)

You probably know a lot more about this than I do, then — I just know what I pick up by reading bits and pieces
There was quite a thing with the Buccaneer regarding controlling the boundary layer of air over the wings. I remember being taught the the vortex generators were introduce to control the boundary layer. They even taped air from the engines to blow air over parts of the aircraft as well.
Problem I have is I was trained on fixed wing theory of flight, trained on fixed wing maintenance - then they sent to work on rotary wing with no theory or practical training on them. So all I have is memory of training from over 55 years ago.
I know the soviets were big on wing fences but from memory, can't think of a UK aircraft using that technology to control airflow.
G
I’m not sure, but I think wing fences are the earlier, simpler technology and vortex generators came in later when high-speed aerodynamics were better understood?
Those clever bods at English Electric didn't bother with wing fences or vortex generators for the Lightning, they put a notch at two thirds span on the leading edge, very clever! Take a bow Ray Creasey!
Miko (not as streamlined as I used to be)
If I recall the EEL didn’t need fences or vortex generators as it was nearly all thrust!! That and a mere ½ degree angle of incidence kinda negated any need for boundary layer control!!!!
The build is looking nice Jim. And the level of technical chat is nothing less than impressive. I wish I was qualified to join in.
I'm not sure about that? I'm quoting Roland Beamont EE chief test pilot, I have quite a collection of his remarkable books.
However ogival wing design negates the need for all such devices with the work of Dietrich Küchemann and the largely uncredited contribution of Johanna Weber who anonymously quietly changed the world! Recommended read for sure
Miko (a list of uncredited women in science and engineering research would make an interesting thread in itself as well as a 'great' group build)
