The Cirrus Dart is a specialized super-high-performance kit and should only be used by experienced high power fliers.

This high velocity, 38mm minimum diameter dart is capable of extremely high altitudes with relatively small motors. Perfect for "H" and "I" class altitude attempts.
The Cirrus Dart is a specialized super-high-performance kit and should only be used by experienced high power fliers.
The Cirrus comes with...

  • Pre-slotted phenolic airframe
  • G-10 fibreglass fins
  • Pre-weighted solid nosecone
  • 7.5" Payload Bay
  • Piston ejection system
  • Ultra-light nylon parachute
  • Pre-cut 6 oz fibreglass reinforcement cloth
  • Explicit instructions

 Don`t let its small size fool you, this is NOT a "model" rocket! In fact, this rocket can attain higher altitudes than a 4-inch diameter rocket using a "K" motor; and at a small fraction of the cost. See the Motor Specifications Chart in the Spec Sheet section of our website for performance information. This is not a "Skill Level 1" rocket kit. To keep a high velocity, minimum diameter rocket like this together during flight, several important construction steps must be strictly adhered to. But don`t worry, everything you need (except for adhesives and paint) is supplied with the kit. Very explicit, step-by-step instructions are supplied as well. A good quality epoxy laminating resin will be required in addition to your regular 5-minute epoxy (EPY-5MIN). A HAMR motor retainer is not recommended for the Cirrus kit as it will disturb the airflow by projecting beyond the sides of the airframe, negatively impacting the purpose of the Cirrus, low drag and high altitude.

Specification:

Diameter: 1.5" | Height: 44" | MMT: 38mm (Minimum Dia)
Parachute: 18" | Payload: 7.5"
Fin Array: 3 | Fin Thickness: 0.06"

The CIRRUS is a potentially Mach busting kit for Pre-Cert & Level 1 flights. This rocket stands 44" tall, is 1.5" in diameter and has a 3 fin design. This rocket comes standard with a 38mm (Minimum Dia) motor mount and can fly on F thur I motors. At ~18 oz., the 18" 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.

    Motor Recommendations | More Specifications

    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.
