This is a very small kit from Composite Warehouse, but one of several Lotus rockets from 2.27 / 54mm  to an 8" version.  

For this rocket I added about 32g of nose weight to get about 1cal stability with the 29/40-120 casing. I didn't epoxy in the nosecone shoulder this time, instead I used a plastic rivet so I can remove the nosecone bulk plate to add or subtract weight from the nose end.
