With the longer propellerhub I took the desition to manufacture a 50mm longer top skin, more margins for DZUS fasterners. I used 6061-T6 0,63mm, just as the eariler. I will use a doubler under skin. Underneath side-skins I aslo placed a 0,63mm doubler, painted with Rand-o-plate green primer. Skins will be cut to proper length, when cowling are mounted.
