2016-09-05: Mounted the jigs again and bondoed them to the bottom skin. After cure I will turn the whole wing upside down and start the top spar cap.
2016-10-02: Glassed the top spar cap. 2 hours preparing for this step, including masking the wing and cutting all the glass. 4,5 hours to finish the spar cap afterwards. Used the plans amount of spar tape. The spar cap is slightly high, I suspect that the spar cap through is not quite deep enough. I will however just contour the top wing and live with this as many claims that the spar cap often gives a flat spot on the wing.
