Quantum Leap 3000

Quantum Leap 3000

Regular price $389.95

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 Interstate 3000 staging coupler system, is a completely modular two-stage rocket. Once you assemble the four basic components, you can combine them to make any of the five rocket combinations and can change to any configuration in minutes. The new Interstate 3000 system is much easier to prep and use than the previous interstate coupler design. The IS3000 comes complete with timer mounts and a remote safety switch.

Both stages have...


  • Pre-slotted Quantum Tube airframe
  • G-10 fiberglass fins
  • "Kwik-Switch" motor mount
  • Piston ejection system
  • Nylon parachute

    Also included...


  • 12" payload section
  • Plastic nosecone
  • Interstate 3000 stage coupler w/electronics bay*
  • Explicit instructions

For more details on CPR3000, go to the CPR Systems page.

Due to the incorporation of CPR, the multiple configurations of the Quantum Leap II are not available.

Interstage Coupler...

Interstage Couplers are used to house staging timers and to connect the upper and lower stages together. The Interstage 3000, the latest version from PML, is used in our two-stage rocket kits. Using an IS3000 system from PML is a quick, simple solution to an often difficult design problem.

  • Easy to assemble
  • Easy to prep
  • The standardized design allows easy timer swapping into other 3000 equipped rockets.
  • Designed to be used with the Perfect Flite Timer4.
  • Includes everything shown in drawing "Interstage 3000 System" below, except timer.
  • Easy to follow, detailed instructions


Interstage 3000 Coupler Detail


*This rocket is intended for experienced flyers only! A good understanding of the proper motor selection and staging techniques is mandatory when flying any multi-stage rocket. 


Diameter: 3.0" | Height: 91.5" (fully configured) | MMT: 54mm Kwik-Switch
Parachute: 48" & 30" | Payload: 12"
Fin Array: 8 total | Fin Thickness: 0.06"

The QUANTUM LEAP II is an awesome two-stage kit for Level 1 and 2 flights. This rocket stands 91.5" (fully configured) tall, is 3.0" in diameter and has an 8 total fin design. This rocket comes standard with a 54mm Kwik-Switch motor mount and can fly on H thru J motors. At ~116 oz. (fully Configured), the 48" & 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.

    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.
