Great collection of birds.. Have you thought of maybe adding this one.. http://www.geocities.com/CapeCanaveral/Launchpad/5249/mdcrane.htm I don't know if there is a kit for it out there but I've never scene a model of it. I think it's the largest helicopter of it's time in the world. Built by Howard Hughes. It tops out at 9m from ground to top. That's 27 feet people. That's while it's still on the ground. It looks like a flying Tarex truck. Howard was clearly part of the "Go big or go home" crowd..
