It is a nitro 44 frame. 12 inch rear wheel base. Modded predator 212 with a .625 bored carb, mod 2 cheater cam, 18lb valve springs, billet fly wheel, billet connecting rob, and a fuel pump. Running gassoline. I don't know exactly how much it weighs but I'm guessing around 100 to 125lbs being that I can pick it up my self. There is a 55 tooth axle sprocket and a 19 tooth drive sprocket on the clutch. Cheezy1
