PUBLIC MISSILES QUANTUM AIRFRAME TUBING 2.1 INCH

Public Missiles Quantum Airframe Tubing.

Quantum Airframe Tubing

Public Missiles Quantum Airframe Tubing

Public Missiles Ltd. exclusive Quantum Tube airframes are the best choice for most sport rocketry applications. QT is very easy to work with and finish, with no spiral grooves to fill. It`s very strong and the best choice for most rocket flying. It is also very forgiving of rough handling and resistant to the impacts of harsh landings. However, QT is NOT a replacement for fiberglassed phenolic; it is simply an easier-to-use material in applications that will not be exposed to transonic or supersonic flight. QT should not be used in minimum diameter applications as the severe heat from the motor casing may adversely affect the airframe.

When to use Quantum Tube:

With any rocket 2.1" through 3.9" that will use an internal motor mount tube and will not fly faster than 0.85 mach.

For any rocket 2.1" through 3.9" that may encounter rough handling or hard landings.

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 our PML kits in the 2.1”-3.9” diameter range (except Nimbus) now ship standard with Quantum Tubing.

Some customers have thought that QT is a replacement for ‘glassed phenolic. This is not the case. Quantum Tubing is not intended for super-high-stress applications. It is intended as a replacement for standard phenolic for sport rockets. QT makes it easier and faster for flyers to achieve a nice finish, and to eliminate some of the problems of plain phenolic in high-impact situations like landing on rocks, cold-weather flying, etc. ‘Glass-wrapped phenolic is still the best product for high stress flights.
