Stock one is plastic and I want the one naturally rc has he has mentioned this group and I would like to buy that part. Look at his video and also I want to know how to bend the front steering rod like he did. I am not liking my stock rtr barrage and want to make it better. I have ordered a metal gear waterproof servo and I need to switch to a 22 teeth gear instead if 18 like in his video. Reply to my email. Thanks
