Image Credit: Project Air/YouTubeHave you ever wanted to set a land speed record? Well, YouTuber James, who runs the ProjectAir YouTube channel, did just that in 2023 with a remarkable jet-powered RC car that ended up being worth more than the actual car he drove.James has crafted some amazing vehicles over the years, and the jet car he built in 2023 actually became the Guinness World Record holder for the world's fastest jet-powered RC car. Sadly, the chassis was destroyed after the wind blew it off course on one of its runs. Now, however, James is back, and he has been building RC Jet Car 3.0.This is set to be something very special. James said it is a "carbon fiber missile," and it involves partnering with Easy Composites to craft a carbon fiber monocoque chassis for the RC car. That is some serious commitment. "Oh, it looks so good with the wheels as well. It's like a Formula 1 car mixed with a missile," James said in his video.The car made its debut ten months ago, and it was as fast as you would expect it to be. While James refrained from going for a world-record run at his first attempt, he was still able to get the car up to some seriously impressive speeds.This Was a Very Impressive Custom CarCreating such a bespoke machine, especially using such high-end materials, was always going to add to the overall cost. In fact, James did stress that point in his videos about the car. "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," he said.It certainly had an incredibly good-looking finish, and you could describe it as flawless. With the fate of the previous car in mind, James was not ready to unleash all of the car's performance in one go. For the shakedown runs, the YouTuber installed a smaller "80-size" turbine engine into Jet Car 3.0. He had designed the chassis to take a "220 size" turbine, a bigger engine with a lot more performance under the hood.But the last thing you want to do is ruin a car on its first runs. The YouTuber took the car to a Radio Operated Scale Speed Association (ROSSA) speed event, and he hoped he could break the 94mph record he had set with the car in its previous incarnation. That would have been a remarkable achievement; however, there was always going to be some teething problems with the brand-new car. James encountered a few of those as he put the car through its paces.How Did the Car's Shakedown Go?Image Credit: Project Air/YouTubeInitially, James put the car through some shakedown runs at 25 percent throttle. It looked good, but there were a couple of niggles. The steering was a bit twitchy, for example, but the YouTuber was able to keep the car under control. James had fitted dual-disc brakes to the missile on wheels, and they could easily bring the car to a halt. The next two days saw him slowly ramp up the speed at the event.During the final run, James got the car up to 111.73km/h, or 69.43mph, which was incredibly respectable for a car during its first outing. James, however, decided not to go for the world record during the event. "One of my primary objectives for this record attempt was to bring the car home in one piece," he said. "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." We wonder just how fast the car can really go.If you want more stories like this, follow Guessing Headlights on Yahoo so you don't miss what's coming next.
