Hypertek L-class Hybrid Motors
The Hypertek L-class hybrid rocket motors provide an affordable per flight entry into L-class High Power Rocketry. The Hypertek system also introduces the unique benefit of a pyrotechnic free ignition system, utilising instead, an electronic spark ignition system.
The Hypertek L-class hybrid rocket motors are available in Hammerhead L-class configuration, which includes a 4.375" diameter Oxidiser Tank, and the New 75mm Hammerhead L-class configuration which enables both the combustion chamber and the oxidiser tank to fit into a standard 75mm (3 inch) diameter airframe.
3 of the L-class motors are mid-range L-class motors (The Hammerhead L-class), and are available with the different diameter oxidiser tanks. There is an additional L-class motor, the near full L-class Earthquake L-class hybrid rocket motor, named because of its earth shaking lift-offs! Again, as with the other 3 Hypertek L-class motors, the Earthquake L is also available with different diameter oxidiser tanks.
