Hobby-grade cars are customizable, which makes them a lot of fun. If you want more speed or a less bulky frame, you can simply tweak the vehicle yourself. You need small tools to do this and lots of concentration. There’s also the possibility of taking your car apart and not being able to get it working again, so make sure to consult the internet or experienced hobbyists before you start. You can add or remove battery power to increase your car’s speed as well as change out tires and other moving mechanisms for more control around curves. The possibilities are endless.
