Thanks Mark, and Robert.Cheered me up for the night
A hanger buddy and myself went over carbon fiber compared to KR
fiberglass. The results are simple. The weight savings for the entire
airplane will be aprox 7lbs and abotu 4X the cost. The entire airplane's
fiberglass is around 25 but around 18 with carbon fiber. That seems a minal
weight difference to pay 4X as much. If im missing something could I be
cleared up. I know Mark L has used carbon fiber for his wings and other
parts.
