Scratchbuild 80" WS Depron Vulcan B2
Thread starter's only
Yeah, It's big!
The mat cutter ensures a clean 90 degree cut
Some of the nose section component parts cut from 6mm Depron
The nose section components 'notched' and ready for dry-fitting. The box section (top) is the battery tray.
All parts dry-fitted
Progress to date. All formers and notched sections glued in place.
Underside of nose section
The nose section with the battery tray in place
Picture 1. My main reference picture today!
The A4 tiles that carried the relevant measurements made life much easier to work out the formers required for the cockpit.
Nose skinned (not sanded yet) and the cockpit area notched out ready for the formers.
Cockpit formers dry fitted
Thought it best to paint the inside of the cabin black before I sealed it all in.
The acetate sheet (scored and folded) and the 3mm depron window frame ready for a lick of green paint before installation.
What a mess but never mind, it'll all be enclosed before too long!
Acetate and painted window frames installed. Looks much better!
Ready for some lightweight filler now.
Bomb aimers window bulge
Rear section of fuselage (behind cockpit) has now been skinned.
After a light brushed coat of grey acrylic.
Clearer to see the the section at the rear of the cockpit
Spot the fuz parts
Ribs cut, fuz formers ready for cutting
Pic 2. The fuselage formers with the carbon rod through the centres. Nicely aligned which should make life easier when the time comes to assemble the fuz.
Formers, ribs and card ducting fitted (rear view)
From side (wing root ribs notched and fitted)
Location of bulkhead where nose meet fuselage correctly aligned.
Side view, everything glued and wing root ribs in place
Nose section laid in place
The vertical tail stab which incorporates the fuselage rear vertical section.
After measuring, removal of the end of the tail at the location of the motor mount.
The round plastic motor mount with 6mm plywood ring with captive nuts in place.
Motor mount glued in
Vertical tail stab dry fitted showing motor mount at rear
Checking alignment of motor bolts
The complex shape of the Vulcan's tail section.
Strengthening spars and ribs fitted to the stab and rudder removed.
The rudder and the 1/16" ply control horn face plates
The control horn fitted
Hinges slotted in but not glued yet
Tape-covered 3mm depron sheet cut roughly to shape of vertical stab. Small amount of pre- bending was needed at the leading edge before fitting.
Vertical stab and rudder skinned
Location of rudder servo and conrtrol horn
The tail end section with parachute release bulge.
The right intake showing the laminated 6mm diagonally cut depron before sanding
The additional spars/ribs fitted on top of the intakes (hollowed out)
The additional ribs fitted between the wing fence and the fuz
The left-hand top intake sheeting curved and ready for glueing.
Top sheeting of intakes done.
Progress to date.
The wing joiner in place. Servo extensions in place
Topside skinned and vertical tail stab test fitted
Bit of detail added to tail
Dense pink foam block with 1/4" x 1/4" hardwood bearers epoxied in place. Light ply top pieces (hole cut for servo) cut and ready for glueing on.
Simple mechanical retract unit fitted.
Wing root thickness showing that the depth in the wing will be sufficient to house the retract unit.
The undercamber at the wing tip can clearly be seen in the 3 outer ribs
Couldn't resist this picture
Wing components jigged up on building board.
Wing drawn onto 3mm Depron skin prior to cutting out and glueing
Wing underside (inboard elevons clamped in place)
Top view of wings. Still covered in tape to protect from 'dings'
I ought to change the title of the build log. The wingspan is actually 82"
Starting to take on the shape of the Vulcan now.
Plywood control horns glued into the inboard elevons
Pink foam wing tip blocks epoxied and ready for shaping.
The location of the retract
The type of hinges I'm using
The component parts of the outboard elevon
Wing control surfaces finished and ready for installation into wing
the 6mm Carbon Tubing strengthener which is epoxied into the wing
Location of wing joiner and strengthener (note the brass tubing towards the LE passes through the foam block under the retracts)
Inboard and outboard elevon servos and their covers
The location of the wing servos
Underside of wings skinned
Pretty pleased with the result. Nice and smooth!
ESC fitted in the tail. Left exposed for cooling.
The motor cover was staring me in the face!
Really tough disposable cup makes for a good motor cowl.
The skinning of the underside of the fuz.
Removeable hand launch point cover (before being skinned)
The cover should hide the launch handle when ROG take-off's are happening.
Ready for skinning
The 3mm Depron exhaust pieces for the top of the fuz.
The 3mm depron rolled ready to make the exhaust tubes on the underside of the fuz.
The half tube sections glued in place
Me and my cups.....a clear plastic one this time makes for perfect exhaust cowlings.Ligthweight Aluminium tape is stuck on the inside of the cup.
Don't they look good?
Fuz primed with light grey artists acrylic paint then sanded down with fine emery cloth
Need a bigger garden!
Work starts on front retracts tomorrow
Dont you just love that shape?
A beautiful trouble-free climb out
Awesome - just awesome!
Ready for her maiden
All checked over. Pilot's gone to the toilet!
Carrying her out to the flightline
Majestic Climb Out
Could swear I heard those Olympus Engines
Low pass for the camera
I promise I will paint the underside
An old pen was used for the refuelling probe. The cap, glued into the nose of the aircraft allows the probe to be unplugged whilst in transit.
Once painted in the correct grey should look quite realistic.
Just enough pressure on the sharpie pen to 'groove' the depron skin.
Smudging of the lead pencil to add the effect of oil staining on the elevator
Reasonably effective I think......
The model just loosely slotted together for the picture to show the whole of the upper panel lining. (wings not secured)
Steer clear of the birds!
I don't tire of looking at this model in flight.
One very happy flier!
70mm fans drawn to scale at the correct locations on the fuselage's largest former
15:10hrs at Finningley
It's sorta ......BIG!
Space is at a premium so I've been relegated to the summer house
The cored-out tail stab
7ft 4" from tip to tail
Coming along nicely
Top of the starboard wing. Retracts fitted, Two carbon wing strengtheners installed. Most of the flat plate of the wing will be removed before skinning with 3mm Depron.
The wiring 'pockets' in the wing root to house the servo extension lead plugs
It's all too much for the dog!
Parts of the rear cowling removed to ensure cooling of the motor. Look closely and you will see the bomb bay door slightly ajar.
2 circuits later and safely down............now to get her finished!
Weather not good but here she is with her new coat of paint and decals.
She ain't heavy - she's my Vulcan! - Photos by Charles
Into the haze.....
Steep banked climb due to an awkward wind direction at our flying field
clear of the trees - climbing out
a perfect sky
Near perfect conditions apart from a gusty wind
Bomb doors opening
Lest we forget - the Vulcan's Remembrance Day poppy drop.
Just some of the great guys at Doncaster and of course, the lovely old lady herself - XH558. You made my day!
How lucky am I?
One of my friends added the caption " I told you to put it on a cooler wash!"
Starboard wing showing the huge amount of under-camber on the L/E
Looking forward into the cavernous bomb-bay
Not easy to see up into the cramped cockpit area so spare a thought for the crew.
The first flight of the Vulcan this year.
