Nitrorcx.they have all the nanda raptor parts. They call it the Exceed madbeast. They are 2 bucks a piece. Just bought one. Hobbypartz also had them. Also listed under madbeast. Or Asiatees.under raptor. Don't give up yet. That's a tough truck. Sounds like the gear mesh was incorrect. Your welcome to shoot me a pm anytime for help.
