Thanks! Using the Intairco trays helps a lot if I do end up retaining a load of the air system for the doors, at least everything can be easily accessed with the nose off.
I've not seen anyone really come up with a good way of electrifying the speed brake, so if that has an air system it's no massive hardship to retain the full air system for the doors as well. It just would have been nice to come up with a solution to run electric gear and and the electron type controller I have with the Mephisto that will then sequence all the doors etc as well.
