This is a very small kit from Composite Warehouse, but one o' several Lotus rockets from 2.27 / 54mm  t' an 8" version.  

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