Great pics.  I have gotten side tracked since I stalled my ME109 after take off yesterday and had a crash landing that pushed the landing gear up through the wing.  I cut the top sheeting off and fixed the rib and bottom sheeting with liberal amount of titebond II.  I would have used epoxy or CA but now am seeing that titebond is equally strong and lighter.  I then had to cut some 1/16 sheeting and get it to fit etc.  The end result was pretty good - strong, and not real noticeable.  So not too much progress on the Extra -  The landing gear plate and 1D are epoxied in and everything looks good.  I have no doubt your pictures will be very helpful since I have not built a belly pan plate before.</p>
