As I cannot prime the fuselage parts, I decide to tackle the empennage tips.
The vertical stab tip is the easiest to adapt. It has to be closef off. I'll do it by inserting some foam, the add a layer of glass cloth, and finish with some filler.



The upper part of the rudder is more tricky, there is some cutting and sanding to be done.



To finish the session, I glue some aluminium strips on the backside of the tip so as to allow a better grip for the rivets.
