Our take on the ARRMA 1/7 LIMITLESS 120 8S BLX SPEED MACHINE RTR w AVC

The ARRMA Limitless 120 is a 1/7 scale ready-to-run RC speed car built for one job: going very fast on smooth asphalt. It comes factory-assembled with a Spektrum brushless system, an EXB center differential, and AVC stability control, and it runs on your choice of 6S or 8S hardcase LiPo (battery and charger not included). Out of the box it clears 70 mph; swapping in the included high-speed pinion pushes it past 100 mph, and adding the supplied center spool and trimmed aero package prepares it for 120+ mph runs. That makes it far more capable than typical 1/10 bashers, but also far less forgiving: it needs a large, clean, flat surface and a driver who respects the throttle.

Best forSpeed-run enthusiasts chasing 100+ mphExperienced RC drivers with 6S or 8S LiPo gearLarge parking lots and closed airstripsHobbyists who like to tune gearing and aero
Pros
  • Ready-to-run with Spektrum brushless electronics
  • Three speed setups from one box: 70+, 100+, and 120+ mph
  • EXB center differential and metal drivetrain parts
  • AVC stability control helps keep straight-line runs planted
  • Includes high-speed pinion, center spool, and trimmed aero package
Cons
  • Battery and charger not included; 8S hardcase LiPos are a real investment
  • Needs a big, smooth, empty surface to be safe
  • Fragile in a crash at speed; body and suspension take damage
  • Not a basher: poor on grass, gravel, or rough ground
  • High speeds mean short run times and fast tire wear

What reviewers say

Owners treat the Limitless 120 as a purpose-built speed platform and praise its out-of-the-box electronics and the flexibility of three gearing setups. Most criticism centers on the surface and space it demands, tire wear, and the cost of feeding it 8S packs.

What people mention
  • SpeedPraisedOwners say it hits its claimed speeds with the high-speed gearing and stays controllable.
  • ElectronicsPraisedThe factory Spektrum system is seen as capable and ready for 8S without upgrades.
  • Surface needsCriticisedDrivers note it only works well on large, clean, flat asphalt.
  • Tire wearCriticisedRepeated speed runs chew through tires quickly.
  • DurabilityMixedThe drivetrain holds up, but crashes at speed cause costly damage.
  • Battery costCriticisedRunning 8S means buying capable hardcase LiPos and a suitable charger.
