Steve,
QLK's is the pattern kit brand of Hobby Barn in Tucson. A nice fellow by the name of Rob is producing them from the original molds they had back in the 80's. Basically, Hobby Barn is "open" again. They have very nice Arrows too: the Super Arrow (more traditional in length) and the Arrow 800 (more akin to the Granat with a closed pipe deck and side tucks in the rear of the fuse to allow cooling air to exit. Exhaust is directed downward). The Arrow 800 evidently has 800 squares of wing area. There are threads here with pictures of the molds and fuses.
I don't have Rob's contacts off the top of my head but a quick search here should reveal them.
David

That didn't take long. Full Super Curare build thread.
Rob's RCU handle is "hrdflite". Call him though, he's not very good with RCU PM. Here's the full info:
