While at one of the local hobby stores I found the hull of a Engel USS Darter hanging on the wall. I checked with one of the employees and he said that the hull had been there for a long time and had more parts. He then produced a box that had the instructions, prints, rails, guns, control surfaces, and a set of what looks to be Engel 750 piston tanks with a TA control(servo controlled), all new in the box. If anyone is interested, the kit is at Dollhouses Trains & More in Novato, CA. There phone number is (415) 883-0388 Ask for Mike.
