The Speed Monster: 120+ MPH is Just the Beginning
This isn't your average RC car—this is the ARRMA LIMITLESS™ 120. It’s built for people who think 100 mph is the warm-up lap. From the moment you fire it up, you're holding the keys to the fastest production RC ever built. The Spektrum Firma 160A Smart ESC and Firma 1450Kv brushless motor work in tandem to handle the sheer power you’ll be throwing at it. Not to mention, the dual cooling fans and heatsink ensure this beast doesn’t break a sweat while reaching jaw-dropping speeds.
Not satisfied with just 100 mph? The included high-speed pinion gear will catapult you past 100 mph with ease. But why stop there? Dial in the aero package and swap out the center spool for some insane tuning options that’ll push you well beyond 120 mph. Hold on tight—because once you start, there’s no turning back.
An Unstoppable Build That Can Handle It All
ARRMA doesn’t just build fast cars—they build cars that can handle the speed. The 3mm anodized aluminum chassis is built for durability, reinforced with a center brace for added strength. The EXB differentials and all-metal gearbox internals ensure that no matter how hard you push it, your drivetrain stays intact.
Big bore oil-filled shocks mounted on black-anodized towers give you total control on any surface—whether it’s smooth asphalt or loose gravel. Pair that with the dBoots Hoons all-road tires, and you’re ready to tackle anything in your way.
And of course, this isn’t just about performance—it’s about style. The low-drag, factory-finished body comes in aggressive colors that scream speed, while the front splitter and large rear diffuser ensure you stay glued to the track, no matter how fast you’re going.
Smart Speed Control
Don’t let the sheer speed scare you off. The Spektrum DX3 transmitter comes with a throttle limiting feature that lets you scale things back until you’re ready to unleash the beast. When you're finally prepared to go full throttle, the 6-channel Spektrum SR6200A DSMR receiver with AVC® technology keeps your LIMITLESS™ 120 stable and straight, even when you're hitting top speed.
The Ultimate Speed Experience
The ARRMA LIMITLESS™ 120 8S BLX is more than just a car. It’s an experience—a 120 mph experience that will redefine your understanding of fast. Whether you’re dominating the asphalt or pulling insane speed runs in the open fields, this is the RC car that lets you rewrite the rules.
So, what are you waiting for? Drop in your 6S or 8S LiPo, point it toward that long stretch of pavement, and let the world catch up.
