Furuppi RC posts the Kanto RC Masters RDX-class final from Tsukuba RC Park

A final is the one run of an event where the judging actually gets tested, because by then the field has been cut to the drivers who can hold a line under pressure. In a tandem format each driver leads one run and chases one: the lead sets the judged line and the clipping points, and the chase is scored on matching that line with angle and proximity. What this material does not establish is whether Kanto RC Masters runs its RDX class that way, what its judging sheet weights, or how a tie is resolved. YAW has not seen the organiser's rules, so the format is reported here only as the general shape of RC tandem competition, not as this event's rulebook.

The same caution applies to the class label. "RDXクラス" reads as a chassis class built around Reve D's RDX, the brand's RWD chassis released in 2023 as kit RKD-RDX, but the posting says nothing about what the class mandates — whether it is chassis-restricted at all, and whether a spec tyre is in force. Drivers looking at the car itself can start with the Reve D RDX manuals and setup sheets, including the maker's gear ratio table and blank setting sheet; the class rules themselves have to come from the organiser.

The venue is better documented than the event. Tsukuba RC Park, at Yatabe in Tsukuba, Ibaraki, is Yokomo's own track and headquarters, long known as Yatabe Arena and renovated in 2022 with an air-conditioned drift course alongside a touring-car track. Yokomo sells springs in a "P-TILE (YATABE ARENA)" spec, which points at P-tile for that drift surface — but what the course was laid out and running for this particular final is not confirmed in the material here, and neither is the result or the names of the two finalists.
