Question about Tamiya 110 Electric Ford Mustang GT4 Kit

The previous speaker has already answered everything.
I would recommend another set of ball bearings right away. This is not a must, the car also runs with the slide bearings supplied. With ball bearings, the car drives a little faster and, above all, there is no wear. a very inexpensive and, in my view, worthwhile tuning.
This one fits: Tamiya TT-02 ball bearing set 16pcs

The motor and the electronic speed controller are included in the kit. You also need a transmitter (remote control) and a receiver and a servo for steering the car. To make the car run, you also need a battery and possibly a charger. You also have to buy the paint for the car separately.
