HPI's Stage-D24: 67.5 degrees of steering and a spool, at 1/24 scale

• Scale and drivetrain: 1/24, rear-wheel drive
• Front suspension: independent
• Rear suspension: T-bar
• Rear end: three-gear transmission, spool diff, 37-turn motor
• Hardware: aluminium motor mount, rear CVD driveshafts
• Maximum steering angle: 67.5 degrees
• Adjustable: front and rear track width, wheelbase, steering linkage
• Gyro: settings changeable from the transmitter
• Body: officially licensed 2024 Toyota GR Supra hard body, 16 parts, clear windows and light buckets, in Prominence Red and Metallic Dawn Blue

That is the whole published list. Tire material, surface recommendation, ride height, spring or oil specification, gearing and battery are not in the source.

A spool locks both rear wheels together, which is the standard arrangement on 1/10 RWD drift chassis for a reason: rotation stays predictable and angle holds instead of being traded away one wheel at a time. Seeing it specified rather than left as a gear diff option is the clearest sign the Stage-D24 was not adapted from a small-scale touring platform.

The 37-turn motor is a high turn count, meaning a low-rpm-per-volt wind. At this size, where wheel diameter is small and the layout is short, delivery and control matter more than outright pace. The source does not state the ESC, battery, pinion or spur, so there is no final drive ratio to quote.

67.5 degrees of maximum steering is generous by any measure — 1/10 RWD cars are often quoted past 60. But available angle and usable angle are different numbers. How much of it a driver can actually carry depends on Ackermann, KPI, caster and how the gyro returns the servo, and none of those are published here. The adjustable steering linkage at least means the geometry is not fixed at whatever the box gives you.

The rear T-bar is the biggest departure from 1/10 practice. On a YD-2 or an RMX you tune the rear with shock oil, spring rate and droop; a T-bar rear puts much of that behavior into the plate itself and how it is mounted. The source does not list what T-bar tuning parts exist, so treat rear tuning scope as unconfirmed until HPI publishes the parts list.

Every modern RWD drift car runs a gyro — it reads yaw and feeds counter-steer correction to the steering servo, because at this scale a person's reactions alone are not fast enough to catch the car. The Stage-D24's listed feature is that gyro settings can be changed from the transmitter, which is how gain is normally handled on 1/10 cars, on a dial or an auxiliary channel.

What the source does not say is whether a gyro is included, whether it is built into the receiver, or which unit it is. For a small-scale platform that matters more than usual, because physical space for a separate gyro, receiver and servo is tight. Do not assume one way or the other from the wording.

At 1/10 a drift body is clear polycarbonate, painted from the inside, window masks pulled, decals on the outside, arches trimmed to suit ride height and wheel offset. The Stage-D24's body is described as something else: an officially licensed 2024 Toyota GR Supra hard body of 16 parts, with clear windows and light buckets, offered in Prominence Red and Metallic Dawn Blue.

That changes the build path. A multi-part hard body arrives in its color, and detail work becomes assembly and finishing rather than backing-coat order. It also changes what track width and wheelbase adjustment are for: at this scale, getting the wheels sitting correctly in the arches under a fixed hard body is exactly what those adjustments buy you.

On the published spec alone, the Stage-D24 is aimed at a driver who wants RWD drift geometry — spool, big steering angle, adjustable track and wheelbase, transmitter-side gyro control — in a car that can run somewhere a 1/10 layout will not fit. It is not a substitute for a 1/10 chassis at a drift park, and nothing in the source frames it as one.

What is not confirmed is as important as what is: whether it ships as a kit or RTR, what electronics are in the box, when it is available and at what price. None of that is in the material, and the surface and tire question — the thing that decides whether a 1/24 car is drivable on your floor — is not addressed either.
