Designer of the UCD was a salt water angler
I think the UCD is a cross between a fun-fly (wing), a Cap 232 (Elevator/Rudder arrangement), and a Dorado, the dolphin fish (fuselage). When I took mine out of the box, all i could think of was hooking it on an offshore fishing trip back in fl LOLOL. That long tall, narrow fuse looks just like a 30 lb dolphin. hehe If I could airbrush, id love to recover mine all chrome monokote, and paint it up to look like a dolphin, having the chartruse, blue , greens and yellows become irredescent, like fish scales. The fish is aptly called a slammer, because of the way they slam the bait, and more importantly, the way they thrash around in the cooler once caught. Would make a great vinyl sticker in place of the UCD stickers for a name. Or even the Hawaiian name, Mahi-Mahi. lol. See attached image for similarities.
