Good finition, works very well.
Bonne finition, fonctionne trs bien.good quality but is this made from metal? i dont know :)I'm using this on an old Traxxas Ruslter that's been upgraded with a 2000kv brushless system. It fits fine with the stock traxxas gears, and the truck has risen from the dead after 15 years of neglect. Good gear at a great price.avoid, its plastic! should be removed and everyone refundedNot steel as claimed.
