![]() 2574 forum posts 1591 photos | After a resent visit to the Great Orme, North Wales UK in June this year 2014, the occasion was to attend and take part in the Jet Provost Mass Build event and great time was had. Whilst there I met Matt Jones who had built a JP, however he also took along his white Avro Vulcan, what a fine looking model. Well I can't think of anything better than build my own example and enjoy flying it on the slopes. I've always enjoyed seeing the Vulcan throughout my life, and to enjoy one up the slope just makes the sport of slope soaring better. Well after studying photographs, drawings in the back of books or on the net, I have finally decided on a size, to make it. This is my build thread for the Avro Vulcan B2.

![]() 2574 forum posts 1591 photos | First made some practice measurements to work with converting the drawing into a ratio measurement I could work with, record my findings and start thinks how I'm going to make it. If you hadn't noticed a big part of a Vulcan is the wing so a lot of time was taken on that and choosing a section thickness practical for both foam use the slope flying.

![]() 2574 forum posts 1591 photos | Next was sparring for the wing and if possible place the main spar on the centre of gravity this helps when setting up and balancing, this can be a compromise because it doesn't place it in a position where it gives full width wingspan support. I will be covering the wing in brown paper and wallpaper paste which gives a little more support and aids decoration. |

You'll be wanting to make a bigger one once you get this flying and see how nice they actually fly. There's never enough model Vulcans, watching this one! |

![]() 2574 forum posts 1591 photos | Next thing on my design mind was the fuselage construction, and I had to walk away for the drawing board. Well solution was found maybe after one or two cups of coffee and it looks like ' back of a fag-packet ' - drawing, however I'll show it because it's all part of the design and modelling process. The drawing below shows the a standard servo even with lugs on ( 55 mm wide ) will fit into the body width. Edited By Mark Kettle 1 on 15/07/2014 19:52:10 |

![]() 2574 forum posts 1591 photos | When I can I try to build into my designs features that allow you to build without always measuring and refitting etc, it doesn't always work, but on the fuselage top and bottoms it does work for this part of the build In this drawing by splitting the top and bottom fuse foam into two 10 mm parts that are glued together, there is a step made and you locate the 15 mm body sides into it, the bottom is done first and after gluing the two top parts together again gluing and placing into the fuse sides to the step. Once the fuselage is stuck together it is shaped like a lot of other fuselages are done here's a drawing to show how you can get a round fuselage in 4 easy steps.

![]() 2574 forum posts 1591 photos | Even at 44" span which really isn't big when you consider some of the Depron sized models made ( 88" and 100" I think I've seen on here) the wing seems to have a lot of mass which for me means a lot of foam. Laid out on the bench, some of the section need to be got ready by gluing two bits of foam together, see how the wing will be cut in parts to get the Vulcan shape.

![]() 2574 forum posts 1591 photos | I made a glider a few years ago that was a bit like the Vulcan, it was a sports epp foam racer, I even decorated it bit like a Vulcan. Here's a link : Edited By Mark Kettle 1 on 15/07/2014 20:23:42 Edited By Mark Kettle 1 on 15/07/2014 20:24:21 |

![]() 2574 forum posts 1591 photos | Close up wing section A (this the mid section) with the line on it for the foam thickness make-up 20 mm with 30 mm of foam on top. Here is the the section up against the the foam block from the middle. Better get on a cut the sections, lots of pinning on section patterns and moving from shape to shape.

![]() 2574 forum posts 1591 photos | Translating the back of the 'fag packet ' drawings into wood patterns for the fuselage epp foam cutting has been done. Foam sides cut notice that wider top and bottom width foam seen here on the bottom piece in this picture. |

![]() 2574 forum posts 1591 photos | After gluing together the epp foam blocks for each wing part, the main wing sections have been cut on all foam pieces and sides to glued dressed up square so make best contact. After gluing all the wing together the wing was allowed to dry a little, 'then I cut it apart again' - the reason was to cut the corner slot where the main spar goes. The spar was dropped on the bottom front edge of the front triangle it was 600 mm long and 10 mm square wood - or 24" long by 3/8" square. seen here in this picture.
