Addiction RC's RX-01: a strut-front RWD kit laid out around an S13

This is a kit, not an RTR. The sellers' lists of what you supply are long, and one item on them is unusual.

• Scale and drivetrain: 1/10 RWD drift, front-mounted motor
• Suspension: strut front, multi-link rear
• Structure: monocoque plus full member frame
• Motor: 380 size required, not included. E.K Motors recommends a MerV-ERA 380
• Wheelbase: 247 mm standard per Super-G, adjustable 240-280 mm with optional center driveshafts
• Battery: short LiPo (Super-G)
• Also supplied by you: ESC, gyro, servo, transmitter and receiver, body, wheels, and a cooling fan
• Part number on the maker's shop: AD-RX01

The 380 motor requirement is the line that changes a parts order. Most 1/10 RWD drift builds are planned around a 540-size can, and a builder moving a shelf of spares across will need to check mount, pinion and fan fitment rather than assume. The cooling fan is listed as something you provide, not as an accessory.

Weight and ride height are not published. Neither are geometry figures: no caster, KPI, camber range or steering angle appears in the retailer or news material I have. For a chassis whose selling point is its suspension layout, those are the numbers a setup-minded buyer will want, and they are not out there yet.

Super-G's product page states it directly: "The standard wheelbase of this kit is 247mm", with 240-280 mm available. A 1/10 RWD drift chassis is usually set up around 257 mm, so the RX-01's out-of-the-box figure sits shorter than that, and the optional center driveshafts take it well past it in the other direction.

The same page lists the kit as "Compatible with our Real Detail Body Series: Supra, S13 Silvia, and 180SX". Those three shells do not share one wheelbase at scale, which is the practical argument for a range this wide: set the chassis to the shell instead of accepting whatever the arches give you. What the page does not do is say which setting suits which body, so plan on measuring your own shell before ordering driveshafts.

E.K Motors lists a "distinctive, race-inspired gear whine" as a feature of the kit. That is worth placing against competition rules rather than leaving as copy.

The R.C.D.C. regulation page — the Japan R/C Drift Community, which runs the All Japan E-Drift Championship at Tsukuba RC Park — allows a 238-280 mm wheelbase and either a 540 or a 380 motor. The RX-01 sits inside both at any setting it offers. The same regulation bans modifications that produce "excessive high-pitched sound", and names what it means: long-head pinion screws, spur work, a bent center shaft, zip ties, resonators.

The rule, as written, targets modifications a competitor makes. It does not address the noise a kit makes as sold, and I have nothing from R.C.D.C. on whether scrutineers would take an interest in this chassis. Do not read the advertised whine as a compliance problem, and do not read it as cleared either. If you run a series with its own sound rule, ask that series.

Plenty of readers never run under R.C.D.C. at all. The relevant question at your own track is whether the layout fits its wheelbase and motor rules and its spec tire — Super-G's own track, for example, runs DS Racing CS3-LF3 on Japanese P-tile.

Availability does not agree across sellers, and it is better to say so than to average it. Read on 29 September 2026:

• The Addiction RC Design shop lists the RX-01 kit as AD-RX01 under 第2ロット予約, a second-lot reservation, alongside 53 spare parts and 10 option parts for the chassis.
• E.K Motors listed its pre-order as sold out.
• Super-G listed the kit in stock.

The three sellers also list three different prices. I am not reprinting a figure here, because a price is only meaningful attached to the seller and the day it was read, and these will move with the second lot.

The spares and options count is the more durable signal. Fifty-three spare parts listed at launch for a first-generation chassis from a maker whose previous output was bodies suggests the support catalog was planned with the kit, not after it.

On the published material, the RX-01 serves a builder who wants the S13-platform layout and Addiction RC's Real Detail shells to govern the chassis, who is comfortable sourcing a 380 motor and a fan, and who treats an unpublished geometry sheet as something to work out at the track.

It is a harder recommendation for anyone who buys a chassis for its known setup baselines. There is no published weight, no ride height, no caster or KPI figure and no shared setup sheet to start from, and the strut front means a YD-2 or RMX baseline will not transfer wholesale. None of that is a verdict on how it drives — I have no basis for one, and neither does any of the material in front of me.
