Interesting that they flew the 17" payload Sandhawk with one of the Nike fin sets on the Terrier. And the overall design really does look like an upscaled Nike Tomahawk.

So I wonder if your drawing above is for the 'BT3' Terrier fins. At least I think that's what the Sandhawk figure reads.
(Edit: It looks like it is, based on converting to metric and adding things up. At least to the nearest centimeter. I looked for RIM-2C fin drawings, too, but didn't find any. But it looks like the RIM-2D to 2F fins would be at least 6cm more span.)


It looks like the Nike-Sandhawk and Terrier Sandhawk would make nice 1/6.5 scale PSII type rockets. Sandhawk with the 2" tube. Nike with 2.5". Terrier with BT80.
