Comments: I've had this XTM Racing Rail buggy for more than a year and had NO issues with the servo .
I've driven this model hard , from dirt to paved surfaces and always had fun .
Broke a lot of parts and worn out others but the servo is still going strong , never had to do anything to it .
It is water proof due to the rubber o-ring at the seam where the two halves of the case screws together .
Wish the rest of the model would hold up as well as the servo .
Keep every pivot point well lubed ( steering , suspension etc... ) and this buggy flies .
