pre-preg is too heavy. It must be TOW. Ciao,

Hi Leo,

I asked Ivan to produce the drawings for INAV a while ago. I also have one of
his hubs and know that the plan spec is correct. I believe that the carbon cloth
used is probably a pre-preg and this sort of cloth is not that hard to find.

Maybe one of the indoor glider flyers can point you in the right direction?
