Other than the flight computer, the most important piece of hardware is the thrust vector control mount. The mount is composed of mostly 3D printed parts and can actuate two solid rocket motor to change the direction of thrust. Once the first motor is done burning, it passively ejects from the vehicle, making room for the landing motor.

AVIONICS
The current version of the avionics system uses a printed circuit board and mostly surface-mount components to achieve a compact design at a low cost. The flight computer is the most important part of the rocket, and makes all of the in-flight decisions.
