Hey guys! I'm new to the mini revo.. I traded my rustler xl-5 for it anyways, I have a weird clicking noise from the drive shaft in the center when I roll my car on the ground and when I run it it make a loud sound as if the driveshaft is hitting something or teeth is missing in the gear? Ive checked the spur,pinion,and the drivetrain but no luck BUT the weird part is that when I take my skid plates off and my t-bone skidplate/bumper the noise goes away? U think my drive shaft is bent? Or is it the gears in the black box that connects the front/rear drive train that's making the noise????
