I spent an hour or so getting the positions of various parts of the luggage compartment correct, amongst those parts I found that I had previously alodined a pair of auto-pilot servo mounting brackets so I did a trial fit of the servos too, all seems O.K. I then masked the main spar carry through & its associated bracketry for priming of mating surfaces, that took quite some time before I was able to spray the primer. Riveting these parts together is planned for tomorrow.
