Yes, the kit uses simple snap-together parts and does not require glue, making it friendly for first-time builders and younger hobbyists with some guidance.
Winding the handle for about 30 seconds typically stores enough energy for the car to run for a little over a minute, depending on winding speed and surface friction.
You can personalise the look with the included stickers and experiment with light cosmetic modifications, but avoid altering the gearing or motor unless you understand the impact on balance and safety.
