The X-CALIBUR is the perfect kit for Pre-Cert & Level 1 flights. This rocket stands 46" tall, is 2.2" in diameter and has a 6 unusual fin design. This rocket comes standard with a 38mm motor mount and can fly on G thru I motors. At ~32 oz., the 30" parachute is sized right for the stock kit to make a safe landing under most field conditions. This kit comes standard with our exclusive Linear Rail Lugs for use with 80/20 brand launch rails. The stock airframe is ideal for flights up to approx. 0.85 Mach.

Below you will find a number of upgrade options. Upgrading the parachute size may be necessary if you intend to build heavy or have a hard landing surface (i.e. gravel, pavement, desert playa, etc.). Some motors will accelerate this rocket to transonic or even supersonic velocities. Under these conditions, this kit may require the fin upgrade, foam encapsulation of the fin root, as well as other advanced construction skills.

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 download and read the PML FAQ and/or consult with a NAR or Tripoli certified member to ensure your flights are fun and safe.
