Unleash Absolute Speed – ARRMA® LIMITLESS™ 120 at Aerobertics
Ready to obliterate every speed limit you’ve ever respected? The 1/7 scale ARRMA® LIMITLESS™ 120 isn’t just fast—it’s a full-blown speed revolution. Straight out of the box, this RTR monster doesn’t ask politely; it demands attention, laughs at 100 mph, and dares you to go faster.
At Aerobertics, we know thrill-seekers crave power, precision, and reliability—and the LIMITLESS 120 delivers all three. Drop in your choice of 6S or 8S hardcase LiPo, add a charger, and you’re holding the keys to the fastest production RC ever built.
Three Ways to Dominate SpeedThis latest LIMITLESS evolution gives you ultimate control over your velocity:
Factory-assembled EXB center differential and gearing: ready for 70+ mph chaos.
High-speed pinion swap: unleash 100+ mph street dominance.
Full high-speed pinion with center spool and trim aero package: prepare for 120+ mph face-melting runs that make everything else feel pedestrian.
Electronics That Mean BusinessPowered by a Spektrum™ electronics suite, this beast handles whatever voltage you throw at it. Features include:
Firma™ 160A Smart V2 ESC with IC5 connector, teamed with Firma 1450Kv brushless motor (heatsink + dual fans).
Waterproof Spektrum S665 metal gear servo delivering 277.75 oz-in torque at 7.4V.
Spektrum DX3 2.4GHz transmitter with throttle limiting—start safe at 50% or 75% before unleashing full fury.
Spektrum SR6200A DSMR receiver with AVC® technology to keep you on track at absurd speeds.
ARRMA Toughness Meets Precision EngineeringThe LIMITLESS 120 is built to survive the extremes:
3mm anodized aluminum chassis with center brace for unrivaled durability.
Optimized 4X4 drivetrain for 8S power with EXB differentials and all-metal gearbox internals.
Big bore oil-filled shocks on black-anodized towers paired with dBoots Hoons all-road tires for grip on asphalt, grass, or gravel.
Factory-finished low-drag body with adjustable wing trim for balanced downforce and max speed.
HIGH-SPEED STABILITY
The 34T Mod 1.0 spool combines with a bearing-supporting rear center driveshaft to reduce drivetrain vibration. Stiff front springs and sway bar improve high-speed handling, and a wide rear track increases stability.
FACTORY-FINISHED BODY
This ready-to-run version of the LIMITLESS includes a low-drag body that's factory-finished in a choice of colors. Wing trim lines can be used to reduce downforce. The full-width front splitter improves traction and handling, and a large rear diffuser reduces turbulence and drag.
dBOOTS HOONS TIRES ON SPEED WHEELS
Big bore oil-filled shocks on black-anodized front and rear shock towers keep the dBoots Hoons all-road tires firmly planted for maximum traction. The tires are mounted on Speed wheels with extra-durable hubs.
SPEKTRUM ELECTRONICS
High-quality, factory-installed Spektrum electronics are ready for your choice of 6S or 8S LiPo power. The IC5 connector-equipped Firma 160A Smart V2 ESC is paired with a Firma 1450Kv Brushless Motor with ARRMA heatsink and dual cooling fans. Like the powerful, metal gear Spektrum S665 Digital Steering Servo, the motor and ESC are waterproof for worry-free bashing in any conditions.
The throttle limiting function on the included Spektrum DX3 2.4GHz transmitter lets you limit the top speed to 50% or 75% of its full potential until you’re ready to unleash it all. You can follow how much battery capacity is available on the transmitter’s Smart battery level indicator. The transmitter is paired with a 6-channel Spektrum SR6200A DSMR receiver with AVC (Active Vehicle Control) technology that helps to maintain traction and direction for enhanced stability and control.
