Decided to make a rocket, couldn't find a good spin rocket so I made one.. I haven't launched it yet.. It should work. Uses Estes 18mm B or C engines. Entire rocket with C6-5 weighs in at 3 oz and stands at 510mm (1'9+")

Still a work in progress, the lugs need to be slightly enlarged to fit the 3/16th rods

will upload a video of it flying

This thing should REALLY SPIN FAST

Update

enlarged the ID of the launch lugs to fit better decreased the diameter of the connector on the nosecone for a looser fit.
