The Quantum Tube (QT), is made from a special blended polymer that is extremely durable and easy to use. You will find this new
material easy to work with and very forgiving. Most hobby type epoxies and paints will readily adhere to this material as well. The
Quantum Tube can be squeezed, dropped, or even thrown and will not suffer any damage as can sometimes occur to cardboard or
phenolic tube. The Quantum Tubes are molded in medium gray and have a glass smooth finish. The Quantum Tube does have one
thing missing, the spiral groove! You will appreciate the fact that you no longer have to fill and sand the airframes to achieve the
perfect finish. All PML rocket kits 2.1" dia. through 3.9" dia. come standard with Quantum Tube airframes.
Our larger kits use our kraft phenolic airframes. They can be used as-is or can be wrapped with fiberglass for Level 3 type
launches. We can even glass wrap them for you! See our Airframe page for more details on all of our airframe choices.
Piston Ejection System:
The PML Piston ejection system is the most reliable and effective ejection system ever developed for high power rocketry. You will
never again need to stuff your rocket full of wadding or fiberglass insulation. Partial ejection caused by blow-by as well as burnt
parachutes will become a thing of the past. Also, the nylon/rayon piston retaining strap is heat resistant and vastly reduces the
zip cord effect encountered during early or late ejection by spreading the force over a much wider area than rope or cable. See our
Recovery page for more info on our Piston System, DuraChute parachutes, and shockcords.
We have also developed several systems that allow the use of altimeters for chute deployment either in a single chute or dual
The precision molded plastic nosecones combine high strength, smoothness and ease of finishing.
• HDPE (high-density polyethylene).
• Thicker wall than competitors; less flex, which reduces paint chipping/flakeoff.
• Double shock cord/chute eyelets, which make them much stronger.
• Ridges on shoulder that can be easily sanded to achieve perfect fit; shoulder also provides better sealing, like piston rings in an
Our high quality plastic nosecones are standard with all rocket kits 2.1" dia. through 3.9" dia. Kits in other diameters come with
nosecones made of either urethane or fiberglass. Click over to our Nosecone page for more details.
Highest quality, professionally made, multipanel, 15 degree conical design, rip-stop nylon construction. All PML parachutes have
a spill hole at the apex to reduce sway and drift. The spill hole provides straighter descent and reduces swinging or rotation of
rocket under the chute while on descent; the swinging occurs with non-spillhole chutes due to the chute trying to dump air. See
G-10 is a highly compressed fiberglass laminate in a high-temp epoxy resin. It is extremely tough, waterproof, and solvent-proof. It
is very rigid, yet has just enough flex to keep it from snapping under a load. When scuffed with sandpaper, epoxy bonds readily to
it, and primers and paints adhere well to it too. Fins can be made much thinner (much less drag) when made of G-10, and still be
stronger than most other materials especially wood. It is a very consistent material and does not have any of the hidden structural
flaws that wood may have. Click over to our G-10 Fin page for more details and to see the HUGE selection of fins available.
Public Missiles Ltd. was the company that first introduced Kraft Phenolic airframe tubing to high-power rocketry in 1989. Phenolic
tubing is a resin impregnated, spiral wrapped, and heat cured tube. It is much stronger than cardboard tubing, with almost 5x the
compression strength. PML Phenolic tubing is heat resistant and is highly recommended for motor mount tubes. Check out both
