First shot is the fixed up rudder horn assembly. Rivets are OK but look at the horrible paint job. All that excess primer will make the plane go 0.01 knots slower :-(
After the rudder horn fiasco, it was a pleasure to attach three further ribs with pop rivets. Unfortunately I cannot complete the assembly yet as I still have to figure out what to do with the two enlarged holes in the rudder spar thanks to my earlier mistake.
