rcmonkey.jp, the daily log where RLAARLO's XDX diff turned up

ラジコンもんちぃ is a Japanese radio-control news site that posts maker and shop announcements as they appear. The material gives no names of the people running it, no base and no start date, so none of that is stated here.

On 25 September it reported RLAARLO's explanation of the LSD on the RWD drift car XDX, tied to the maker's video titled "You'd Usually Upgrade to This. XDX Already Has It.| RLAARLO RC Drift Car XDX". The diff is described as standard equipment on the car.

The claims, as the post relays them: at low throttle the LSD allows a difference in rotation between the left and right rear wheels, and raises its locking effect when the throttle is opened. RLAARLO says that holds down one-wheel spin and steadies drive to the rear, and that it stabilizes rear behavior while holding angle and through left-right transitions, with the two rear wheels working together more readily when the throttle goes in at corner exit. Those are the maker's statements, not a measured result, and the post does not give the diff's internals, fluid or any setting. An earlier item on the same site, the XDX teaser, notes two bodies are prepared for the car.
