I've got a simple one I can send offline. Two "pages". First page is unbuilt, lists manufacturer, kit, and location, which for me is pretty important since I have a poopload and have trouble finding 'em. When I start working on one, the location goes to "bench".
Second page is finished birds, has mfgr, name, length, weight, chute, motor combos with estimated altitudes.
I also have pivot tables that offer up summaries of each, so I can see how many unbuilt kits I have by manufacturer, for example, as well as built ones.
Too big to post here, though--over 500 built ones now, probably in the neighborhood of 400 unuque unbuilt. If I added competition models, it would really be long
