A Saturday meet at MST circuit, read from the post that recorded it

The post says the writer attended 土晩会 at MST on the Saturday of the previous weekend, and that he helped run the proceedings together with タケやん. He also says he ran himself.

A compact chronology, with the one inference marked:

• Saturday, September 26, 2026 — the meet, if 先週末 (last weekend) is read the usual way against a Wednesday publication date. The post does not print the date itself.
• Wednesday, September 30, 2026 — the entry goes up on the R31HOUSE RC blog, numbered as part one of a Kansai-to-Okayama sequence.

The writer thanks 運営の皆さん — the organizing crew — and MSTサーキットさま as separate parties in the same sentence. That is a small detail, but it is the kind that saves an archive from a later tidy-up: on this evidence, the venue and the people running the night are not necessarily the same party.

The post lists a top three in 追走 — the chase, which is to say the tandem battles, lead and chase, rather than solo qualifying:

Three names and three placings. No bracket, no judging breakdown, no count of how many pairs reached the battles. A results list this short is common in blog-era event reporting and it is still the better record, because every line in it came from someone who was there on the night rather than from a reconstruction.

The most useful sentence in the entry is not about who won. SHIBATA⚡221 writes that the night went very アットホーム — homely, in the sense of relaxed and unintimidating — and that it covered 大会形式やマシン操作について: the competition format, and machine operation. From ちびっこ, little kids, through to adults, everyone could enjoy it.

Read literally, that describes an event where the rules and the handling of the car were part of the program rather than assumed knowledge. For a scene whose competition vocabulary is inherited wholesale from full-size judging — lead and chase, line, angle, proximity — a meet that stops to explain its own format to a nine-year-old is doing something an archive should notice. It is also the kind of thing that leaves almost no trace unless somebody blogs it.

Plenty, and it is worth being exact about it rather than filling the gaps from habit.

The post does not state the surface, the layout, or whether the walls and clipping points were changed for the event. It does not name a scale or a class, a chassis, a body, a gyro or a tire rule, and it does not say whether a spec tire was in force. It gives no entry count and no judging criteria beyond the fact that 追走 produced a top three. It does not say where MSTサーキット is, and the title's Kansai-to-Okayama framing describes the writer's weekend rather than a single venue.

None of that is a failing of the post. It is a participant's note written for people who were already there. It becomes a problem only when a later retelling treats the silences as detail it is free to supply.

The ① in the title is a promise of at least one more installment covering the rest of the trip. Whether it arrives, and whether it adds the venue detail this entry leaves out, is a matter for the blog rather than for guesswork here.

What survives from the night as published is modest and firm: a Saturday meet, a co-run program that taught its own format, a writer who ran as well as hosted, and three names in the chase order. Everything beyond that is still waiting on a source.
