Jeff,

what about a 14 oz Hayes and a 2" nose wheel?

Mmm... no 14 oz and the 12 is only 1 mm shallower. Pretty tight quarters in there.

The only idea that occurs to me is to use a 2 tank setup with the main behind the wing LE former feeding a 2 oz in the tank bay.

You could also alter the profile of the fuse front bottom... heresy?

Oh, you might have to forget the hatch with retracts or make the retract fuse bottom opening removable. I did that on a small model.

David.
