Yep you can use one as i have one in mine, all depends on what servo you run etc, you may find that you have clearance problems with your saver and the body and undertray, you can either a- cut a hole in the body and tray ( i tried this first with mine but no good for outdoors) or b- shorten the servo mounting posts by 3-5 mm or until the servo sits right up to the lipo, this should give you enough clearance on your saver side, there is no real science to this just use a file you will know when it looks right
