RE: RC10GT Sand Setup???
I would advise against it because it will be very harsh on the truck. Be careful with sand it will tear your truck and engine apart. IF you really want to then make sure you run an air and fuel filter and make sure they are good ones. Cover the reciever and try to cover the outdrives they make a special cover at rc10gthobby.com or melt some heatshrink over them. Clean it very well after you run it by taking it apart somewhat, check the bearings because i'm sure sand will get in there and eat them up.
