Fins attach at 2 points. Inside the airframe it's bolts & nylon lock nuts through the vertical spars. Really this is so solid I doubt the external ones add much but they don't hurt. Outside, it's short bolts and low profile nylon lock nuts through the fins (not yet installed - finishing that up later today) and vertical bolts down into the tee nuts in the spars. Very solid. It better be, the 1st flight will be on an 11,000ns N4000
Wow, exceptional work Jerry. The Sandhawk was one my favorite rockets growing up although I never managed to build one. I'm adding it to the queue....
