Hey. I've been following your bat-stuff... quite nice. I don't have all the time I used to in which to build and comment (grad school, life, etc.) but I do look at most things that cross my path. I really dig the scale your building at and the challenges building at that scale entail. As for the half-pin gap, I think if I ever revisit that plane (it's still together) I will use this technique I picked up from Kelso http://mocpages.com/image_zoom.php?mocid=280094&id=/user_images/5162/1310670846m
Keep up the good work in the MocOlympics, I'm going to try to comment on the first round builds this weekend.
