Public Missiles Ltd #

Description

The CALLISTO is a great kit for Pre-Cert and Level 1 flights. This rocket stands 46 in. tall, is 2.2 in. diameter and has a 3 (Nike Style) fin design. This rocket comes standard with a 29mm motor mount and can fly on F thru I motors. At ~25 oz., the 24in. parachute is sized right for the stock kit to make a safe landing under most field conditions.

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.
