All. I have discovered that I made an incorrect statement in one of my replies. I went searching on the net, and have just found another article from a reliable source regarding this UAV, which states that "it was derived from the Dyn Aero MCR.4S". The original source that I used for my challenge made no reference to this fact, so Trevor, please accept my apologies...you were closer than you thought, and even closer than I thought you were! It explains why the MCR.4S came up in your search.
