Moulded wing progress?

Have you built another moulded wing from the mould you made recently Josh?

Hey Jim- yeah i have! Its a 2 metre this time with an RK40 foil, same as a d60. Im pretty excted about it. I was gonna go pretty light but I just ended up going for mid/ heavey weight. Mostly glass but with loads of carbon in the spar caps (like six 1" strips of unicarbon fabric, overlapped in the middle third for each cap) and a carbon / foam noodle shear web - you shoul try it, its way easier than cutting/ sanding bits of end grain balsa!
Skins are 2oz glass/ 6oz glass /1.5mm balsa/ 6oz glass, which seems about as stiff in a squeeze test as my d60 wing.
AUW is about 1100 grams and now about 1250 with all the sevos and wire etc.
Stiffness wise its heaps better than my double glass opus or my erwin dss (plus a lot lighter than the erwin)
Here's some pics.
