The local B&Q in Portsmouth has the pale orange equivalent in stock in 2'x4'x4" ( i think its 4") at about £7 a sheet. Its in the roofing insulation section. Sands just as well as the blue foam..

Technical name is Extruded Polystyrene Foam as opposed to Expanded Polystyrene Foam. Easy to spot the difference from 10 paces, Expanded is the original packaging and is comprised of big bubbles (Like in bean bags) bonded together. Extruded has a smooth unbroken surface.

Blue foam has now been "Greenified" and is Pink! Mentioned the B&Q stuff a while ago. Cut with hot wire, scalpel or saw with Bread knife, Sand and seal with Emulsion or skim with paper/card.

Trivia for OZ users.

In Oz, the colour denotes its density, in other words how soft it is.
It is commonly referred to as foam rubber and is available from very soft, pale yellow to almost rigid, dark green and used by florists for floral arrangements as it holds water very well in the flower arrangement.

From memory it disintergrates, turns to dust, over time.

I think you may be referring to "Oasis" used by florists, a very different sort of beast. The colour blue was the Dow-Corning product I believe and the pink colour was from an other manufacture, I may be wrong there but Oasis the water retaining green stuff is meant to hold water but the blue foam absorbs less than 1% after being submerged for a year. It is used in the construction industry as a base for pouring concrete on etc. The Oasis can be crushed in your fist. Read the Sheffield Insulations pages, the B1 grade is the finest "grain" and is the most dense.

I went to my local B&Q and i could not find anything suitable i called into Wicks on the way home and i found some its a foam type known as kingspan there are others names for it but its all the same stuff thanks for the helps guys I have been doing some more today the pilots cabin has been made and the mast and support and also been made both are removeable to allow for ease of transport the mast and box can go in the side cabins but the pilots cabin will have to be in a box with the pylon when i get round to sorting one out

Tim , check the Yellow Pages for your local Sheffield Insulations depot. Find out from them if any building sites near you have bought any blue foam and go on a scrounging mission for off-cuts, take the model with you

There's a SI depot in Leeds Tim. Last sheet of Blue foam I got from them was a damaged piece and took a lot of convincing them it would be OK for my use. Nearly had to break his arm to take the price of a "Drink". Since your making big flat areas, you should have a look at using "Depron" sheets. This is EPP - Expanded polypropelene sheet and is being used in preference to Balsa on large scale toy Aeros.

I will have to go to the depot in Leeds as for the use of Depron i am not a fan quite easy to damage and EPP does not give a smooth finnish when painting

more work has been one i have made the fins which are removeable for transporting the model i have also made/used the foam i was after for the front of the model i have put a skim of filer over and sanded more is required to take out and dents one done i will paint on some PVA thinned down with water to seal them

hover tim · « **Reply #35 on:** February 04, 2012, 04:08:57 pm »

more has been done i have mounted the lift fan and done some of the detail work she is going well

unbuiltnautilus · « **Reply #36 on:** February 04, 2012, 04:12:56 pm »

Tidy looking lift fan, I have seen similar in a locally owned SRN6, worked well too.

hover tim · « **Reply #37 on:** February 04, 2012, 05:03:30 pm »

the fan was made on a cnc,lasercutter,milling machine so far better than done by hand

hover tim · « **Reply #38 on:** February 07, 2012, 05:42:56 pm »

any info on the SRN6 i have got a few thoughts of who it may of been

unbuiltnautilus · « **Reply #39 on:** February 08, 2012, 03:48:23 pm »

Belongs to my mate Ahmed and built on the Isle of Wight by...can't remember his name

Really impressive model, although your BH7 is starting to look like it will give the SRN6 a run for its money!!

hover tim · « **Reply #40 on:** February 09, 2012, 05:50:37 pm »

ahh yes it was built by Mark Porter on the IOW and Ahmed added sale deatil and working puff ports.Many thanks for the coments about my Model

unbuiltnautilus · « **Reply #41 on:** February 10, 2012, 09:25:52 am »

Noisy little sods, those puff ports

hover tim · « **Reply #42 on:** February 10, 2012, 06:32:30 pm »

yes there EDF fans mounted in the model i dont think they are needed really and its more weight for the model to carry

hover tim · « **Reply #43 on:** February 12, 2012, 05:58:26 pm »

Hover Tim · « **Reply #44 on:** April 09, 2012, 05:27:04 pm »

Hi Tim.

Interesting build. Really looking forward to seeing how you make the "skirts".
Colin

Hover Tim · « **Reply #48 on:** June 03, 2012, 03:56:58 pm »

the skirt will be subcontracted but i do know a bit about skirts what interests you

colin-stevens · « **Reply #49 on:** June 03, 2012, 05:38:23 pm »

Hoping we are both refering to the same type of Skirts here. I was looking forward to how you would design the skirt to get that "bulbuous" effect.
