Carbon fiber if 3-4 times stronger than Eglass. However, the wing construction of the KR2 does not call for 3+ layers of Eglass, so you will only add cost. Alternatively, you could consider using the construction methods in "Advanced Composite Techniques" by Zeke Smith. I hope to build a wing panel using that method sometime in the next year for test purposes. I expect it to be both lighter and stronder.
