KR> advice

[travis]

I want to use 5 oz carbon fiber mesh for the entire skin of my kr2 project 
including the boat I'm not using plywood for that like the plans call for I 
will put a layer on both sides will that be enough or do I need to put 2 layers 
on both sides? and will 1 layer on the inside and 1 layer on the out side 
enough for the wings? thank for any advice
