Unfortunately, I no longer have the box or manuals, and I'm no RC expert, so I don't know the specs. Comes with a new 4000mAh 7.2v battery. I've upgraded the original Mechanical Speed Controller (which is included) to the Hobbywing Quicrun 1060 Electronic Speed Controller. It pulls a bit to the left (I'm sure this can be easily fixed). The chassis had cracks towards the rear body mounts (as pictured in the 8th and 9th photos) - these were repaired by fusing them back together, but they still hang a little. Any questions, please feel free to message me and I'll do my best to answer them. This item is in the category "Toys & Games\Radio Control & RC Toys\RC Model Vehicles & Kits\Cars & Motorcycles". The seller is "badgerlik" and is located in this country: GB. This item can be shipped to United Kingdom.
