Tony Whittingham Posted May 10, 2018 Share Posted May 10, 2018 Hi all, my kit seems to have part of the instructions missing. There’s some details of the assembly sequence I don’t understand with regards to the nacelles. They each come in 2 halves labeled in pairs, 1,2,3,&4. Should I glue both parts 1 together, and so forth? Or, is each nacelle, for example the inboard composed of a part 1, and a part 2 to take into account the wing taper? If anyone has built this kit and can clarify this, I would be most grateful. Also, does anyone know what the dihedral angle on the main plane is?

Jure Miljevic Posted May 10, 2018 Share Posted May 10, 2018 Hello TW According to drawings, published in Charles Woodley's book Bristol Britannia, wing dihedral is 3°. Unfortunately I do not have Airways kit so I cannot help you with instructions. Cheers Jure Link to comment Share on other sites More sharing options...

wallyinoz Posted May 12, 2018 Share Posted May 12, 2018 Hiya Tony, Built one a while back..build progress here: https://www.britmodeller.com/forums/index.php?/topic/235015778-bristol-britannia-vacform-subject-name-change/&tab=comments#comment-2613778 You do have to account for the wing taper, a lot of trial and error cutting fettling and filling is required to get the nacelles in the right spanwise location, in the correct alignment fore and aft as well as up and down, the wing "holes" may have to be oversized to allow placement without distorting the quite flexible vacuform piece when sliding the items onto the wing all the best with your build, it is the best vacuform I have ever played with cheers wally 1 Link to comment Share on other sites More sharing options...
Flankerman Posted May 12, 2018 Share Posted May 12, 2018 I built one about a gazillion years ago - and concur with 'wally' about the engine nacelles - lots of fettling to get the airfoil shape cutouts in the nacelles to match the wing cross-section. The inner 'hole' in each nacelle has to be slightly bigger than the outer hole - to allow for wing taper. I can remember making the Proteous exhausts from suitable diameter brass tubing - 'squashed' into an oval shape. The model was finished in A&AEE colours - as part of my clubs 'Bristol Collection' Good luck with your model Tony... Ken 1 Link to comment Share on other sites More sharing options...
Tony Whittingham Posted May 13, 2018 Author Share Posted May 13, 2018 Thanks Wally and Ken, I’ve looked at your marvellous examples, and those will be a tough act to follow. I was planning to cut bulkheads and spars from 0.060 sheet, and hang the main gear from the rear spar. Thanks to all of you for the guidance on this one. I estimate 9 months to complete.

TW I never had this particular kit but as vacform/short run kits go... It would be logical to think that the two halves marked 1 go together to form Number 1 engine but do dry tests before you commit to glue. Regarding fettling, I suggest that you tape sandpaper to the wing surface and run the nacelles against it, this way you should obtain a matching cutout easily. Keep up the good work!
