Avro Vulcan 1100mm in 6mm Depron

About

This Avro Vulcan design was a gift from Kepa in Finland who created the plans and made them free issue.

This post is to offer further help and guidance to anybody looking to build this stunning model. I have looked at
several other designs and feel that this is by far the best!
Thanks Kepa good work!

Printed Plans cut out for templates….

Depron cut out carefully with a box cutter knife.
I would recommend that the top skin is not cut out as the plan is undersized especially at the front leading edge

Note the thin ply added either side of the spar to offer rigidity and carbon fibre rods added for good measure

The cockpit is made from a section of plastic pop bottle and the nose is a front section of a 70mm
propeller spinner and looks great

Parts list from HobbyKing UK
28 series 2200Kv with 6×4 prop so less nose weight requires and 1kg thrust…..oh yes
1x #TR-UBEC/28160 TURNIGY 3A UBEC w/ Noise Reduction (UK Warehouse) = $4.76
2x #DMG16/28416 D-MG16 Metal Gear 2.9kg/.08sec/18.8g (UK Warehouse) = $19.44
1x #TST-SBEC55A/29645 TURNIGY TRUST 55A SBEC Brushless Speed Controller (UK Warehouse) = $23.55
1x #AM2002-30×10/34423 30CM Servo Lead (JR) 32AWG Ultra Light (10pcs/set) (UK Warehouse) = $3.61
1 x 70mm black plastic prop spinner (for nose cone)

Time and care must be taken to ensure the motor mount is strong and secure. I actually used balsa
and carbon fibre rods epoxied in. The adapted folding prop was a must to save on landing disasters

The top skin is covered in masking tape to stop surface tear when shaping depron to form the wing.
Depron is quite rigid but becomes more supple when manipulated. Care must be given to avoid
snapping or cracking.

Additional masking tape is added to keep shape until glue has set. Over night is best.

First flight resulted in a heavy nose landing. Taped up damage adjusted and second attempt was successful.
Time to build a new nose section…….

D
amaged but not terminal…. we can rebuild him

IMG_3209
New nose section reinforced with balsa and opening for battery so it can extend forward into nose to tune centre of gravity.

A bottle of wine and few hours later its repaired and good as new.

Flew it the following day….COG perfect and really stable flight

CENTRE OF GRAVITY

Use the CoG 27cm from front of wing (not nose, the root where wing stops and nose/cockpit starts) for ref 33cm from trailing edge and you will be fine.

A trip to RAF Cosford and obtained information on the real deal

Large scale model at the air show approx 20ft wingspan and looked awesome in white.
My model now going to be white!

The real thing flying:-

After seeing the vulcan in white it is time to paint it.

I found in my cupboard a tin of universal primer and tested it out on a piece of depron. being oil based it was a bit slow at trying but gave a good finish where as water based acrylic paint seemed to be a bit flakey and easily marked.

IMG_3548         IMG_3554
I used decorators corking sealer along joints to improve finish.
Now for some finishing touches with engine exhaust tubes.

I got creative with a silver permanent marker

IMG_3603  A sharp blade and I added home made roundels and serial number.
XM607 was the Vulcan that was the backup during the Falklands conflict and become the primary bomber after the lead
bomber had technical difficulties. It successfully bombed Port Stanley.

AND NOW I AM PROUD TO SHOW HER FINISHED IN ALL HER GLORY……

IMG_3631 The reflective tape gives a nice finish.
The motor cowl was the top half of a Dr Pepper bottle with a few vent holes.

31/08/13 at Llantrisant Common, Wayne Taylor thew her up for me. She went ballistic, and I just managed to hold onto her.
A little bit of trim and she was flying. It was over 10mph wind and gusty causing her to be very twitchy. It still felt a little tail
heavy and need to reduce the rates as she was too responsive. The wing design causes a lot of lift and decided the reeds
were the safest option to land. She landed with no damage.

I made a few modifications along the way. Decided that the tail was too heavy so reduced the motor to a NTM series 28mm 2200kv motor from the 3536 I was planning to use. The 2200kv motor provided plenty of power on 3S (2200mA) but my friend has discovered the NTM 28mm 2700kv motor was a little better.

CENTRE OF GRAVITY

Use the CoG 27cm from front of wing (not nose, the root where wing stops and nose/cockpit starts) for ref 33cm from trailing edge and you will be fine.
