Parachute Eject Mechanism

For safe landings

The Parachute Eject offers a reliable mechanism that enables rocket launches at angles ranging from 0° to 50° with respect to the vertical axis. It can be used with any launch system capable of launching PET Bottle Water Rockets.

How It Works


  • The Parachute Eject is designed to screw into a 2L PET bottle, and release a latch to open the parachute bay.
  • The PE mechanism is screwed in place, holding the parachute bay door in place during flight.
  • Once the rocket system is ready for flight, the PE mechanism is turned on and magnetically armed.
  • When apogee is reached and the rocket tilts over, the PE mechanism releases the parachute bay door and the parachute is released.
  • The system resets and stands ready to be armed again.

Key Features


  • Reliable tilt switch based trigger system.
  • Contactless magnetic arming.
  • Lipo battery offering up to 100 eject triggers for every full charge.
  • On/Off button.
  • LEDs indicating power and system armed status.
  • USB Charging.

Have no fear of a failed parachute deployment and get your rocket safely back down to the Earth with the Parachute Eject mechanism.
