If you are running the scorched or generic(Amazon, eBay, etc) roto-lok motor mount, then this gear cover will help protect your gears from dirt and debris! Perfectly shaped to fit around the motor mount and leaves no room for debris to enter. This cover is made from a Carbon Fiber Reinforced Nylon, with heat resistance up to 350 degrees, only available in black! This DOES fit the new scorched motor mount with the third bearing support!!
