Make sure the setscrew on the drive"cup" (nearest thebrake disk)is tight.. But yea, the main setback onRedcat is gonna be thatLHS'smost likely wont have replacement parts.. Although, for somehting like a brake disk, ya might be able to find an HPI or similar equivalent?? I know they (HPI) have some Spur gears for the2 speed tranny,2 speedClutch bell/Pinion, clutchshoes/springs, ect. that'll fit someRedcat vehices..On the plus side, you can get a decent rc vehiclefor a great price, and find out if you really want to run that particular "class" of vehicle.. Do a search on your car (here in the redcat forum) and you'll be able to come up with a list of replacement parts you should have on hand, and be able to make an order and notget beat up too bad on the s&h charges..
