If you're into RC crawling with a Traxxas TRX-4 or similar model, this skid plate (also called a roof plate) is a smart upgrade. Part number is 7817T, and it comes in orange. It's basically a protective plate that mounts to the roof of your RC truck's body to prevent scratches and dings when you flip over or scrape against rocks. Fits specific Traxxas models (like the 77086-4). Installation usually requires some small screws (4x 3x15mm counter-sunk screws are often used). Keeps your hard body looking better for longer. Made from durable plastic. Good for trail runs or competitive crawling. Just check compatibility with your exact model before ordering. A simple part, but it makes a difference if you're serious about your RC hobby.
