Unassembled! The box has some minor damage. An old LiPo battery is included as a bonus. If you have a Tamiya conversion connector, you should be able to use a Tamiya ESC as well. However, it's old, so it's just a bonus. It worked fine when I used it last year. Thank you for your consideration! 1/10 scale off-road racer, Candy Green Edition. - Model Name: The Grasshopper - Edition: Candy Green Edition - Scale: 1/10 scale - Type: Off-road racer - Included: Wheels, chassis, instruction manual Thank you for looking.
