The TETHYS is a robust and versatile kit for Level 1 and 2 flights. This rocket stands 53" tall, is 3.9" in diameter and has a 3 fin design. This rocket comes standard with a 54mm motor mount and can fly on G thru J motors. At ~62 oz., the 50" parachute is sized right for the stock kit to make a safe landing under most field conditions. This kit comes standard with our 1000 series rail guides.

It is prudent to sim your kit/motor combination using the actual weight of your finished model to determine max velocity, altitude, ejection delay, etc. This will allow you to make an informed decision when selecting a suitable motor for your rocket. Please consult with a NAR or Tripoli certified member to ensure your flights are fun and safe.
