Any one adding carbon liminates for spars in there foam core wings?.If so what type and size.Did'nt add any on my tipo I just finished,just used some heavy glass colth about 4 inch wide and 3\32 sheeting.Hope it holds up cause it sure snap rolls nice.The Mach 1 I'm working on has 1\16 sheeting and was thinking maybe some carbon fiber would help,the tipo got a little heavy with the 3\32 sheeting.
