Found a picture of  a nose section I did for a historic BRM using the above lay up. The nose is 2m x 1.9m and plenty strong enough and low weight (compared with the original).

Hi Tom, 

I think the bigger concern is the complexity of the parts you are wanting to mold.  Those fenders look like they will be a pain to mold.

Certainly multi piece moulds, great for getting the grey matter going working out the split lines

my wing is from 9 pieces guys i go normal way as i used budget molds and guy made me but without flanges so i can not do infusion . i think i go with 300gr 3 layers or  1 layer 300 and 6 6oogrnad i put hard foarm before last layer so parts get structural stable things.

i be using this foarm i think that gonna be pretty good and stable.

i asked guys who do boats they told soric eat lot of resin and give very hudge weight. any link for 3d core? its same as soric?

Soric does have a larger resin uptake than closed cell foam but certainly nowhere near as much as the equivalent layers of CSM would. 3d core has less than Soric mainly because the material is different and the cells are bigger so the feed channels between each core are smaller that's why I suggested it.
EC now do 3D core, have a look in the "core materials" section. 3D core is very similar in performance to closed cell foam but it will conform to curves better. That's what is was designed for.
