From the Tamiya description:
This is a factory finished R/C model of a tractor, featuring Kumamon, the PR mascot of Kumamoto Prefecture in Japan, as its driver. The classic tractor design is accurately captured in lightweight and durable polycarbonate, and painted in a Kumamoto inspired color scheme. The chassis is designed with a wheelie bar to enable fun, wheels-in-the-air driving action. The included wheel type transmitter enables smooth control of steering and acceleration.
The set includes a transmitter and pre-installed R/C system, such as receiver, pre-adjusted steering servo and electronic speed controller (ESC).
Requires 4 AA batteries (not included).
