You are correct, I meant 2.4 oz Carbon.
The spar caps will be layed up inside of the sandwich.
Someone else recommended the shear web ahead of the aileron hinge, thanks for pointing that out.
I spoke to someone in the "know" yesterday, and he said that the holes would be fine, but I'd probably have to drill them out every time I used them. I was thinking about drilling and tapping the holes in 1/4 x 20 thread and just screwing in a waxed up bolt so that it was flush with the bottom of the mold??
You'd be suprised how many people are using the wheel collar method on these. Scares me also, thats why I want the holes
Thanks for your help.
