I hear that!! Just might be one of the biggest drawbacks to a rig where the body covers the wheels..add to that the fact that Tekno didn't add a slot in the chassis under the spur gear to eject debris. Still don't understand that one?Yea, I try not to run em when it's muddy. So much fun, but to me, not worth the cleanup! Bad enough with my dusty track just tryin' to clean all the dry dirt and little rocks out!
I actually cut a slot into my ET48 chassis that I swapped my MT410 onto with a die grinder and cut off wheel..LOL. I believe it helps prevent spur gears from chewing on rocks that inherently end up on the chassis.
