Tinkerbell is a scratch built 38.5" long, 2" dia. rocket with a 29mm motor mount. She has a custom 8" nose cone that is a pencil cup holder that I bought on clearance at Wal-Mart for a buck. BT is slotted for TTW fin construction with custom made fairy wings. BT has a custom wrap around finish instead of being painted. I used Open Rocket 15.03 for layout and sims.
