I dont have hybrids, but I do have UE cases with the HB gears. When I bench test the Gmaxx I dont hear any noticeable gear whinning, but then again it would be hard to over the noise of the motor and spur/pinion etc. I would say check it by hand, to see how much slop there is between diff pinion & ring gear, should only be a tiny amount of play in any direction.
