I got this toy at Hobbypeople. It came with body, chassis, motor and worm gears. http://www.hobbypeople.net/gallery/419021.asp
I built the turnknucles and changed the car from 4wd to rwd. Then, the rx, servor and esc were installed. This car was 1/32 scale and too small to fit the battery in. so I left the 6 cells AA battery pack(from my Micro RS4) on the top of the body. I guess I need to install the 2/3 AAA batteries.
