I agree this truck can take the stress of 4wd racing. I had a few rough runs this past weekend with some hard landings... Some my fault other not, but that is racing. I have yet to break any parts on the truck. Very happy with the durability.

One point I want to speak to is the belt skipping issue under heavy brakeing. I have found you can run the belt pretty loose but you have to pay close attention to how much breaks you are running. The RX8 and 550 motors can generate alot of braking force. I have found the best practice is to turn your endpoint down until you cannot hear the belt skip under full throttle to full break (say at the end of a front staight...) I found this setting to be the perfect amount of breaks without locking up the wheels. I was on medium traction track at the time.

Just my thoughts...
