1/7 ARRMA Limitless 120 8S RC Speed Machine Overview
Ready to obliterate every speed limit you’ve ever respected? The 1/7 scale ARRMA® LIMITLESS™ 120 doesn’t just break records, it shatters them, sweeps up the pieces, and asks what’s next. This isn’t your casual weekend basher. This king of the speed demons targets drivers who think 100 mph is just the warm-up lap.
Straight out of the box, this ready-to-run production spec RC car comes locked and loaded with everything you need to dominate asphalt, embarrass supercars, and leave tire marks on your memory. Just drop in your choice of 6S or 8S hardcase LiPo and add a charger, and you’re holding the keys to the fastest production RC ever built. Now you’re ready to unleash peak ARRMA speed potential.
This latest LIMITLESS evolution doesn’t just go fast. It gives you three different ways to send it. Factory-assembled with an EXB center differential and gearing that’ll blast you past 70 mph for epic all-road chaos. Want more? Swap in the included high-speed pinion and watch this beast crank past 100 mph like it’s cruising to the grocery store. Ready to make physics cry? Install that high-speed pinion with the supplied center spool and the trim aero package to prepare for face-melting 120+ mph speed runs that’ll make you feel bad for all the rest.
The electronics package doesn’t mess around either. We’re talking factory-installed Spektrum™ power that’s ready to handle whatever voltage you throw at it. The IC5 connector-equipped Firma™ 160A Smart V2 ESC teams up with a Firma 1450Kv brushless motor complete with heatsink and dual cooling fans. The waterproof Spektrum S665 metal gear steering servo cranks out 277.75 oz-in of torque at 7.4V, and like the motor and ESC, the LIMITLESS 120 is completely waterproof because fast shouldn’t mean fragile.
The Spektrum DX3 2.4GHz transmitter keeps you in command while your brain tries to process what 120 mph actually feels like. Smart drivers use the throttle limiting feature to dial things back to 50% or 75% until you’re ready to unleash the full fury. The 6-channel Spektrum SR6200A DSMR receiver comes loaded with AVC® technology that keeps this rocket tracking straight instead of turning your speed run into an unplanned drift session.
Legendary ARRMA toughness means the LIMITLESS 120 can handle punishment that would turn other RCs into expensive confetti. The 3mm anodized aluminum chassis gets reinforced with a center brace because structural integrity matters when you’re breaking the sound barrier. We’ve optimized the 4X4 transmission for 8S power with EXB differentials, all-metal diff outdrives, and gearbox internals that won’t flinch when the throttle hits the floor. Big bore oil-filled shocks mounted on black-anodized towers keep those dBoots Hoons all-road tires glued to whatever surface you’re terrorizing, whether it’s asphalt, short grass, or loose gravel.
The factory-finished low-drag body comes in aggressive color schemes that look fast even when it’s sitting still. Wing trim lines let you dial back the downforce when you want maximum velocity, while the full-width front splitter and large rear diffuser team up to tell wind resistance exactly where it can go.
Your ultimate speed machine experience starts now. Drop in your 6S or 8S LiPo, point it down the longest stretch of pavement you can find, and prepare to redefine what fast actually means. The ARRMA LIMITLESS 120 RTR doesn’t just go fast - it goes ARRMA fast.
