They are in here if you want to look
I suggest that you tape the fuselage halves together and check the canopy fit when you start

Gad Sir, it's not British! Surely you haven't run out of our aircraft.
More seriously, I have one of these and was checking it out a few days ago with a view to getting started but was a little wary after building the Ye 2a. Are there any toublesome areas?

Excellent. Not something that ever thought of seeing, let alone doing.
How did you make those nacelles?

For gettingthe wings to line up and provide matching dihedral or anhedral I join the wing halves to the fuselage before joining the fuselage halves. By putting each half fuselage flat on the bench and mounting the wing on top of it and then lining them up by eye, using a template or a protractor you can get the halves to match. ( though a bit late for this build)

I can't get any of that to work any differently to my original effort

Has anyone tried using Amazon Prime? It allows you to use a link to share photos but when I try it here all I get is this
https://www.amazon.co.uk/photos/share/R9zt785QcMD3vnmAhDMWYwvw2lwAt3P8GOunZcBKT0P
If you click on it you end up in my Prime account
If I try the 'insert image from URL' the insert box goes pink and nothing happens

Thank you. Pardon a scathing observation about the flipping obvious! Did there not used to be a 'Delete' option as well?
It's like entropy - everything changes for the worse.

Nice work. Some were built in the UK. One regret about my gliding days is that I never managed to get a flight in one. They were said to be a delight to fly.

The site is 'Britmodeller' - no mention of plastic so feel free to show your excellent work.

Thank you for that explanation. My first thought was that it's 60 years since I had any dealings with the mathematics of boundary layer flow and knowledge has moved on since then but then I realised that the 707A was designed about another 10 years before that so how did its designers know that much about the boundary layer?
Regardless of the logic I still think that it does not look right!

I agree with you about the complexity of the wing root/fuselage junction. I reckon that it is even harder to get right when trying to correct an inaccurate wing made from resin.
Regarding plans. After reading your comments about finding different versions from Google I followed the same route with interesting results. I had only Barrie Hygates version to start with and as he referenced the actual a/c, Bae archives and gave actual dimensions I expected these to be reliable but there are some obvious errors, notably in the area of the intake/fuselage junction. Other versions seem to have got the latter correct but have the wrong wing LE sweep.
I am curious about why you did not follow the intersection line on the drawing as this looks as if it would have given the correct shape.

Here is a very rough mod showing what I meant. The intake has been removed and the gap filled with Milliput to show the shape of the wing without the intake. The second picture shows the forward edge cut off.
The red lines show (very roughly) the wing root with the front cut off and the black line in front shows it before the cut off

There is something not quite right about your argument but I can't put my finger on what it is. I agree that it looks as if the nose of the aerofoil has been cut off. I wonder if the aerofoil shape at the root should have a less pointed profile.
where did you get the drawing shown in the first post? It does seem to show the correct shape at the root, something that is not right in any other drawings or models that I have seen.
Is it possible to show a views of your model that show the same aspect as these pictures? Note that the wing/fuselage join appears to be an almost straight line.
I'm trying to get it in 3D using Milliput and sandpaper on a Pro Resin version!

Sorry to rain on your parade but the fuselage/intake junction is incorrect. Have a look at the pictures in here.

Regarding the piloting I had great sympathy for the Stampe formation as it poured with rain just before they took off and thay really got bounced around in the air.

That's all you need. Altimeter? Houses getting smaller, you're climbing. Houses getting bigger, you're descending. The rest you can figure out by looking out the window.
I'm going to start saving.
I think that a rudder might be helpful

Well done for getting any pictures at all, let alone decent ones.
A friend and I got the three day ticket thinking that there would be a fair chance of getting at least one decent day. Ho! Ho!. Despite being dressed for the Arctic we baled out even before the Daks.

At the the time Alpha Delta replied my friend and I were on our way home thoroughly chilled despite being dressed for the Arctic, as the rest of the program did not seem worth dying for.

A really nice picture but the point of the splitter plate obscured the bit I wanted to see however on your Flickr site I found the following which shows that there is no opening. something that, to me, looks most unaerodynamic as it looks as if the airflow meets a blank wall. Anyway thank you many times over. You have been a great help.

Whilst building the Pro Resin 707A I thought that the airflow splitter on the intake looked a little thick so I looked up a picture I had taken of the 707C to see what the real thing looked like and discovered that the intake/fuselage junction on the model was completely wrong (surprise!). However the photo of the 707C revealed something interesting. Behind the splitter plate it appears as if there might be a recess (it could be just the shadow) for another form of intake. Might it be an offtake for the boundary layer? Does anyone have any ideas, knowledge or pictures of that area? I belive that it is the same for the 707A and C.
I have looked at the pictures of the a/c in the Manchester Museum and they are maddeningly inconclusive.
The drawing in Barrie Hygate's book was no help and I suspect may be in error in that region.

Well done. I had my 'dream flight' in a Hunter almost 20 years ago and my heart is still in the air of Gloucestershire...

Bill - A really nice job of a really difficult kit.
To anyone else: I built one of these about 10 years ago. If you read my build notes you will have even more appreciation of his excellent efforts

Regarding getting in and out of the cockpit there is a photo somewhere of the pilot doing just that. By the way, it did actually fly but never reached its Mach 2 design speed but only reached Mach 1.25 before it was cancelled

I just looked at that link and there is a very nice collection of models. I was amazed to see that you had managed to finish the Pegasus EAP. Congratulations - you are REAL modeller
