In the "tired of making corrections for one day" category, 3050 rpms would be in the low 80's for percent power of my normal cruise speed.
Also, looking at the Diehl wing skin installation drawing, it appears as though stock aft spar WAFs (wing attach fittings) are used, so yes, they are apparently the same shape as the regular wing, but with tips molded in, so no CG range change there. Diehl wing installation instructions are at http://www.diehlaero.com/KR-2%20Wing%20skin%20installation.htm . The skins are definitely the ticket to quickly building your wings, and they are almost (if not entirely) immune to the skin bubbling that glass on urethane has because of the way they are laid up and cured (vacuum bagged, I'm sure). Diehl wing installation instructions are at http://www.diehlaero.com/KR-2%20Wing%20skin%20installation.htm . I believe Steve Glover is now making them at nvAero. They also sell wing skins for the "new airfoil", AS5046. See http://www.nvaero.com/products/Diehl-Wing-Skin-Kit.html ...
