Two Cool for Spool



Two Cool For Spool launches like a regular spool rocket but half way through the flight the second stage ignites and the lower disk dropps away while the upper disk flies on. The high drag design makes this the ideal rocket for two stage flights on a small field. Tumble recovery on both stages means a short recovery walk. A fun rocket to fly with lots of smoke and noise on the way up!
