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 fiberglass fins
  • Pre-weighted solid nosecone
  • 7.5" Payload Bay
  • Piston ejection system
  • Ultra-light nylon parachute
  • Pre-cut 6 oz fiberglass 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. Think about it... If recording the highest altitude is your goal, why would you put a 2-ounce altimeter measuring 1.5" x 4" in a 20 pound behemoth to attain a lower altitude? 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. 20 minute Finish Cure Epoxy (EPY-FINISHING) 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.

Quantum Leap II

PML`s "quantum mechanics" have continued to improve one of rocketry`s favorite two-stagers, the Quantum Leap.
The new Quantum Leap II, now with the new Interstage 3000 staging adapter system, is a completely modular two stage rocket. Once you assemble the four basic components, you can combine them to make any of five rocket combinations and can change to any configuration in minutes. The new Interstage 3000 system is much easier to prep and use than the previous interstage coupler design, and is identical in design to the IS3000 used in the Terrier booster stage for our MiniBBX. The IS3000 comes complete with timer mounts and remote safety switch.

| This 2-stage rocket kit is intended for the experienced HPR scratch builder intending to supply his/her own electronic parachute deployment system into the sustainer stage. We strongly urge you not to fly this kit without an electronic parachute deployment system installed into the sustainer stage. Failure to do so will allow the sustainer stage to fall to earth without recovery deployment if the sustainer motor fails to ignite. If you are unsure about designing and installing your own electronic parachute deployment system, consider buying the Quantum Leap 3000 kit, which contains the electronic deployment components (except altimeter) as standard. To purchase a Quantum Leap 3000 kit already equipped with the CPR3000 Dual-Deployment Recovery System, click here.

NOTE: The following chart lists configurations of this kit that may be flown as it is received stock from PML. However, your addition of an electronic deployment system may/will make some of these configurations unavailable, depending upon the design of your system.
