Thanks ,
it gets a little more ducting .
The radar / radio set behind the cockpit will be ram air cooled so there will be another small intake ahead of the canopy .
probably on one side with the fuel filler access opposite .
or , one each side and the fuel door in the center .
..and the air exhaust port near the empennage somewhere .
Form follows function , so once the cockpit tub is attached I'll see how much ducting will fit , what size and profile , still allowing for frames and stringers .
I need to completely finish out that main intake before going any further . That's going to be the trickiest part of this whole thing ,, I think .
