Hi All
I have to thank Matt for his guidance and assistance with my various projects over the last six months or so, I would not have managed without your  help along with this website.
Up to this point I have moulded my own Carbon sheet using various thickness of "Soric" to produce truly professional finished Carbon sheet which I have used in building various Tri's Quad's and Hexacopters, I have also made Canopies used to cover the fragile electronic components, all of which have used the vacuum resin infusion technique.
Now I am going for the totally moulded Quad, 500mm between motors, consisting of a top and a bottom moulded shell, with internal (own made carbon plates).
Up to this point I have used the high density polyurethane foam block as a core to build a pattern, this has now been covered with one layer of 163g woven glass cloth, I will add another layer once this is cured (not sure if I should have used two layers up front).
I have attached a photo of progress of the pattern, I intend to use the pattern to make internal moulds (guided again by Carbon Mods) which I will mould Carbon Fibre shells that house all equipment and hopefully will fly.

I will try to let you know how I go on along the way.

Hi again
I have been working all last week on respraying and polishing the pattern again, so that I can make a new mould with wider flange. 

I have cut a new corex shroud out of two pieces (so that I get the correct width for the pattern, see photo) and taped these together with brown packing tape, then put a tape line around the pattern at the point that I going to encase the first half of the mould, this has been hot glue gunned to the pattern via the brown tape, then I added a fillet of wax from the underside which I have forced through the gap so that the corex is a snug fit around the pattern.

I have now gel coated and epoxy puttied one half of the mould, so I am at the same stage as last time.

I have removed the corex shroud (see photo)and I have to clean up the pattern and mould so that the second half can be moulded (hopefully later today)
One thing I did come up against this time was epoxy putty got VERY HOT (exotherm?) so I had to take this outside to try to cool it, this may have been due to large amount of putty I used (3.5 kg) 

The resulting bottom mould is much cleaner than last time and I hope this will give a good result.

Wish me luck.
Cheers
John
