Cirrus  

Cirrus

 

This is the 2.1 inch version of our popular Black Brant X. The Mini BBX is very close to true scale and comes with detailed painting instructions. The Mini BBX is perfect for Level 1 Cert flights as it flies using high-impulse G through I motors in its 29mm MMT. When you’re ready, the Mini BBX can be retrofitted with the CPR-3000 altimeter-based Close Proximity Recovery system. As if that weren’t enough, the tail cone at the base of the rocket is designed to fit the optional Terrier Booster Stage for a truly authentic Black Brant X two-stage flight. As you may have already suspected, the Mini BBX kit includes a Quantum Tube airframe, a specially designed tail cone, and G-10 fins. The payload bay measures 21.5". 

Features:
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

Quantum Leap II  

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 Mini BBX. 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 Quantum Leap 3000. 

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.
