In the world of high-speed radio-controlled cars, 94.76 mph is a serious benchmark. It's the official Guinness World Record for a jet-powered RC car, set back in 2023 by James from the YouTube channel ProjectAir.But setting that record came with a catastrophic price: on a subsequent high-speed run, heavy crosswinds blew his car off course, completely obliterating the chassis. After taking some time to recover from the devastation, James is officially back with Jet Car 3.0—a carbon-fiber masterpiece designed to shatter his old record and push the limits of RC engineering.The Carbon-Fiber "Missile"To ensure the new car could handle incredible aerodynamic stress, James teamed up with the specialists at Easy Composites to construct a fully carbon-fiber monocoque chassis. Built around the front and rear subframes of an Arrma Limitless, the shell was meticulously formed to house a real miniature jet engine.When the raw chassis was finally delivered to the shop, James was completely blown away by the sleek, narrow design."Oh, it looks so good with the wheels as well. It's like a Formula 1 car mixed with a missile," James laughed. However, the flawless finish also added an immense amount of pressure to the project. "The car was now probably worth more than my full-size car in all of the material, labor, and design work that had gone into it. I better not mess this one up".To play it safe during the initial shakedown, he installed a smaller "80 size" turbine engine instead of the massive "220 size" powerhouse the chassis was ultimately built for.The Runway ShakedownJames packed up the jet car and headed to the ROSSA (Radio Operated Scale Speed Association) speed event, hoping to safely test the car and potentially edge past his old 94 mph record.During the initial 25-percent throttle runs, the jet car looked incredible, though there were a few teething issues. "I was finding the steering to be a bit twitchy but generally the car felt stable," James noted as the dual-disc brakes easily brought the car to a halt.Over the next two days, James slowly crept up the speed charts, tweaking the brake bias and dialing in the steering. On his final run of the event, starting 300 meters back from the timing gates, the car ripped down the tarmac at a highly respectable 69.43 mph (111.73 km/h).The Difficult DecisionTo break the 94 mph record with the smaller engine, James calculated he would need a massive 500- to 600-meter run-up. But with crosswinds suddenly gusting over 20 mph on the runway, he was faced with a tough choice: throw caution to the wind, or pack it up and live to fight another day."One of my primary objectives for this record attempt was to bring the car home in one piece," James explained. "The crash of the previous 2.0 car had been replaying in my mind all weekend and, as you can imagine, I was keen not to repeat this devastating experience".Opting for self-preservation, James officially called off the record attempt, packing the pristine carbon-fiber chassis into his van."It was a disappointing call, and I was gutted not to be running the car at higher speeds, but 69 mph on this car's first time out was actually quite impressive," he concluded.Now that the chassis has proven to be incredibly stable, James is ready to scale up to the massive 220-size engine. When Jet Car 3.0 returns to the runway, the 100-mph barrier doesn't stand a chance.
