Using this Maqueen Mechanic - Beetle kit is super easy. First, make sure you have a Maqueen Lite or Maqueen Plus, as well as a micro:bit board and battery (you'll need to buy them separately). Then, start by installing the metal servo and other mechanical parts with the included screws. Connect the servo to the control ports S1, S2, or S3 on the Maqueen Plus. Once everything is set up, you can start controlling the servo within the 0 - 180 degree angle. As for maintenance, keep the kit in a dry place. If the servo gets dirty, use a soft cloth to clean it gently. Be careful not to over - power the servo, as it may affect its performance. Refer to the tutorial for more detailed guidance.
