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.

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.
The ARRMA Limitless 120 8S BLX Speed Machine is a 1/7 scale, ready-to-run RC car built for high-speed runs on asphalt. It comes factory-assembled with Spektrum electronics installed. You add a 6S or 8S hardcase LiPo battery and a charger.
It has three speed setups. As assembled, with an EXB center differential and the stock gearing, it reaches speeds past 70 mph. Swapping in the included high-speed pinion takes it past 100 mph. Installing that pinion with the supplied center spool and the trim aero package is the setup for 120+ mph runs.
