Kraton HELP! Kraton gears sounds like they are stripping.

[Jimindo]

My kraton sounds like it's stripping in the rear diff but nothing is stripped and my oil is still good but it is stock and I do plan on buying some just not sure what wt. Any thoughts on what's happening?

Video of the sound? Could it be coging at take off?

Video does not want to upload, but it doesn't have much power in the rear end and just sounds like stripping, but nothing is. I don't know what cogging would be?

Brushless, sensorless motors (like come in most all RTR's) tend to shutter a bit when starting and at low speeds. It is worse in some cars than others; most of the Arrma 1/8's are not too bad. Some times I will hear it as the drive line clanks right at start up. Once the truck is moving, there should be no cogging.
