Buddy, the last time I ran my Tmaxx at the beach, the sand got between the clutch bell gear and the spur gear and completely removed the teeth on the clutch bell. And then, I took my Traxxas Revo to the beach and it did exactly the same thing to it. Unless I come up with some type of cover for my gears or a buggy or something that has enclosed gears, I won't be doing that again. And I was running in loose dry sand.
