Squirrel Works Two Cool for Spool

SW-033 – Two Cool for Spool


  • Two Stage Design
  • Laser-Cut Plywood Disks
  • Water Slide Decals
  • Tumble Recovery

Two Cool For Spool launches like a regular spool rocket but half way through the flight the second stage ignites and the lower disk drops 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!

The dual stage spool model rocket is easy to build and ideal for small, neighborhood fields. The bright colors and tumble recovery combine with lots of smoke and noise to guarantee multiple fun flights, minus the long recovery walk associated with more traditional designs
