Joseph,

I made my belly board from several plys of bid to about 1/8"
thickness. At 550 hours of usage it shows no sign of fatigue. I
deploy it for every landing. Board is about 10" x 10".

Yes, that would give it a better contour. If a composite engineer

could offer a carbon fiber layup schedule, that would be great.
Otherwise, some of us newbies will not be able to duplicate the 6-
pack. Aircraft Spruce says the carbon fiber bid is .007 thick. I am
calculating that I would need about 12-13 layers. I can get 12
pieces from 1 sq. yd. of bid. I may have to "wing" it.

Thanks for your help.

I would do the layup on the unblemished belly. After that's

done, then dig

out the foam per plans. I have now idea about the orientation.

Maybe one

of our composite engineers could chime in.

Ok, that makes sense. I could cut out the 10" x 11" skin, remove

1/8" foam,

then vacuum bag the layup. Any idea on orientation of the carbon

fiber

cloth, i.e., front to back, side to side, 45 deg. ? I have never

used

carbon fiber cloth. Should it be Uni or Bid?
