Stan,
I should clarify- the butchered fuselage pieces are in the box, from the Dragon TA-152H with the correct tail. I can make those work, and the wing (if you can call those awful pieces of styrene that!) are there as well. I have a bunch of spare parts from the Tamiya D-9, including stabs and elevators. The Tammy cockpit looks like it will fit with a little finesse. Looking at the project more closely, I think I could get it built with what I have on hand. Every time I think about doing it, I look at the awful wing and quietly put it back into the box.
I think you're right on the D-15. It looks very similar to the 152C-0 with the left side intake and modified cowl. Also has the 152H tail, and the wide paddle blades. There are 4 white metal bits in the box, but no instructions came with it so I don't really know what they are for. Two of them look like boxes for boxing in the shell ejections ports, and the other two are small oval pieces with a curve in them.
