About the Crest RS120 Brushless ESC
Optimized Performance Across Race Modes
The Crest RS120 features three distinct race presets: Stock Racing Blinky Mode for compliance with no-advance timing rules, a 1/10 Off-Road Mode for truck and bumpy terrain applications, and a 1/10 On-Road Mode for high-speed asphalt action. Each mode is pre-calibrated to deliver tailored power curves, enhancing drivability and control. These profiles remove the guesswork and let racers focus on performance.
Advanced Cooling & Technology
Utilizing innovative ultra-thin, windowed cooling N-MOS technology, the Crest RS120 integrates its chip core directly with the metal housing. This engineering feat reduces thermal resistance by 35%, resulting in improved heat dissipation and maintaining 98% energy efficiency. The compact design eliminates bulky heat sinks, allowing for a slimmer ESC that runs cooler and lasts longer, even under demanding race conditions.
Precision Tuning & Data Feedback
With built-in features like adjustable RPM limiting, offline data recording, and independent drag brake and brake frequency control, the Crest RS120 is all about customization. Users can fine-tune their setups in 0.5K increments and analyze performance data via the Cayote BTune ESC Bluetooth Module (CYECBM01 - sold separately) or Cayote Xlink Multifunction LCD Program Box (CYECPB01 - sold separately) with the Cayote APP. This level of precision ensures better handling and strategic insight for competitive drivers.
