The World's Fastest RC Car: Inside the Record

From the September 2026 research edition. Product details and prices are dated source records; confirm the exact model and manual before buying or making changes.

A battery-powered remote control car has officially gone faster than 230 miles per hour. Not a full-size electric supercar, but a model you could lift with your hands, steered by a driver on the ground.

The car is "The Beast," built by Stephen Wallis in the UK, and it holds the Guinness World Record for the fastest battery-powered remote-controlled model car. Since then, Wallis has reported even faster runs with a newer car, though those have not yet been verified by Guinness.

In this post we look at how the record was set, what makes a record car different from anything you can buy, where the unverified runs stand, and how all of this compares with the speed claims printed on ready-to-run (RTR) boxes.

Quick answer

• The Guinness World Record is 377.73 km/h (234.71 mph), set by Stephen Wallis with "The Beast" at Llanbedr, Gwynedd, Wales on September 19, 2025.
• Wallis's newer car, "Mach Reaper," reportedly hit 256.47 mph (412.74 km/h) on June 14, 2026, but he said he had not yet verified it with Guinness.
• The record car uses drone technology: quadcopter motors, a flight controller for stability, and an 18S battery setup.
• The fastest speed claim among the stock RTR cars we cover is ARRMA's Limitless 120 at "120+ mph with included optional speed gearing," a manufacturer claim, not a measurement.

The official record: 234.71 mph

Guinness World Records lists the fastest battery-powered remote-controlled model car at 377.73 km/h (234.71 mph). Stephen Wallis of the UK set it with his car "The Beast" at Llanbedr in Gwynedd, Wales, on September 19, 2025. Guinness says the run beat the previous record by more than 25 km/h.

New Atlas, which covered the record in January 2026, gives the previous record as 351.69 km/h (218.53 mph). We could not find a source naming who set that earlier mark, so we will not guess.

A note on dates

You may see articles saying the record was set "earlier in 2026." New Atlas published its story on January 15, 2026, and some later coverage appears to have mixed up the announcement date with the run date. Guinness's own listing dates the run to September 19, 2025, and that is the date we use.

Inside "The Beast"

Record cars share almost nothing with the RC trucks in a hobby shop except the idea of being remotely controlled. According to New Atlas and Top Gear:

A few terms explained:

• "S" count is the number of lithium cells in series. Each LiPo cell reaches 4.2V when fully charged, so 18 cells in series gives 75.6V. Most 1/10-scale bashers run 2S or 3S; big 1/5-scale trucks often run 8S.
• A flight controller is the small computer a drone uses to stay level. In The Beast, New Atlas says, it is used to keep the car stable.

What stands out is the price. Top Gear's figure of about £2,000, including £380 of batteries, is less than some people might guess for a world-record machine.

The faster runs that are not yet official

Wallis did not stop at 234 mph. He built a newer car called "Mach Reaper," with a four-motor electric drivetrain, and reportedly ran it at Llanbedr twice in 2026:

Wallis himself was clear about the status: "I haven't verified it with Guinness World Records yet." Until Guinness confirms it, the official record remains 234.71 mph. If you see headlines calling the Mach Reaper the "world's fastest RC car," that may turn out to be true, but it is not yet the official record.

How the record has moved

For context, earlier marks were far lower. Guinness reported in 2023 that Nic Case reached 325.12 km/h (202.02 mph) in 2014. The previous record before Wallis, per New Atlas, was 351.69 km/h (218.53 mph), and then Wallis pushed it to 377.73 km/h.

There is also a separate category for jet-powered RC cars. James Whomsley of ProjectAir set that record at 152.50 km/h in July 2023, according to Guinness. It is a different kind of machine and a different record, so do not confuse the two.

Compare that with RTR speed claims

So how fast are the cars you can actually buy? Manufacturers print speed claims on boxes and product pages. These are manufacturer claims, not independent measurements, and they almost always come with conditions. List prices below are as of September 17, 2026, and prices change.

Two things to notice:

1. The conditions matter. ARRMA's Limitless figure depends on the "included optional speed gearing," meaning a gear that comes in the box but is not what the car is set up with. Traxxas's Sledge figure needs a 6S battery (sold separately) and optional gearing.
2. Independent tests can come in lower. Budget cars show the gap clearly. QuadifyRC measured an MJX Hyper Go 14210 at 46 km/h on gravel with a GPS unit, against a 55 km/h claim, and the reviewer thought the advertised figure was "probably a stretch."

Even taking the Limitless claim at face value, the Guinness record is roughly double it. A record car is a one-off speed machine built for record runs. A stock RTR is built to be driven, crashed and repaired.

What to watch out for

• Chasing top speed on public roads or near people. Record runs like Wallis's are made at organized events, such as the ROSSA event at Llanbedr. A car doing 60 mph or more is dangerous to people, pets and property. Use a large, empty, private or permitted space.
• Exceeding ratings. Do not run more voltage than your ESC and motor are rated for, and watch temperatures after speed runs.
• Believing unverified numbers. Treat YouTube and forum speed figures as claims until someone shows the method and equipment.
• Forgetting conditions. A speed claim without the battery, gearing and surface is close to meaningless.

FAQ

What is the fastest RC car in the world?

The Guinness World Record for a battery-powered RC car is 377.73 km/h (234.71 mph), set by Stephen Wallis with "The Beast" on September 19, 2025. His newer "Mach Reaper" reportedly reached 256.47 mph in June 2026, but that run has not been verified by Guinness.

How much did the record car cost to build?

Top Gear reports about £2,000, including £380 of batteries.

What battery does the record car use?

It runs 18S, made from three 6S packs, for 75.6V at full charge, according to New Atlas.

Is the ARRMA Limitless really 120 mph?

ARRMA claims "120+ mph with included optional speed gearing." That is a manufacturer claim with conditions, not an independent measurement we can cite.

Who held the record before Stephen Wallis?

New Atlas gives the previous record as 218.53 mph, but we found no source naming the holder. Nic Case's 202.02 mph run from 2014 was an earlier mark.
