I was using this with a 1/12 chassis, but I'm selling it due to a change in specifications. Please check the condition of the product in the images. If you have any questions or requests for additional images, please ask in the comments (for some reason, the background has become blurred...). This is a used brushless motor, so please refrain from purchasing if you are overly concerned about its condition. I look forward to your purchase. G-Force Team Orion Yokomo
