Drawing of the motor is HERE.
The gear motor is measured to be 7 inch long and the motor itself has a diameter of 2.5 inches. Rated voltage of this gear motor is 13.5 VDC and maximum speed is 50 RPM. Rated output load is 60 watts and output toruqe at 50 RPM is 6 N-m (4.4 ft-lb). Mounting is based on M6 screw mounting.
The wireless controller functions as a reversible momentary control switch from a 12v dc power source. By holding down the right side button, the motor runs in one direction until the user releases the button; by holding down the left side button, the motor runs in the opposite direction until the user releases the button. Current rating is 6 amps. Two transmitters (with batteries) are included in this package. Wireless signal range is 100 ft.
If you know your application requires a high current draw, secondary (high-load) relays are required to make it work. Here's a diagram that uses automotive relays to achieve that:
