Dimple R-904 pieces?.

On page 07-08 for the rudder it calls out what to dimple, and leaves off the list the two R904 pieces. It does say to dimple the attach strip R918, and R904 is sandwiched between R918 and the skin….

So if it is in between two dimpled pieces it must be dimpled I think? Should this be added to the errata?

Yes these need to be dimpled and the plans do not call for it. Adding to the digital plans on the dropbox wiki.
