i finished up a few small details today. first, glued on the wing attachment bolt covers (beside the radiators). then added a couple more smaller bulges (not sure what they're there to cover). then, the prototype had some small airfoil shaped vents underneath the fuselage. i recreated these using K&S airfoil tubing in various sizes.

pic 3-5: then i added the mooring rings on each end of the wing. i used rubber o-rings glued to 1/32" ply for these.
