Rudder skin dimension
Iím building up a new rudder skins and cut a piece of 16 thousandth according to given dimensions. But when l measure how long the skins should be according to the rib R-304 (by measuring from where the two flanges converge to the leading edge of the rib), The skin seems to need 19 inches from the tip of the trailing edge to the spar R-302 while according to SK 7 it should only be 17 5/8 inches.
Any body got any other dimension for the skin.
PS : R-304 canít cut down or changed.
