The integrated 50A 4-in-1 brushless ESC runs deeply optimized AM32 open-source firmware, with higher driving efficiency and lower conduction loss, effectively improving the overall energy efficiency of the power system and extending flight endurance. With native support for DSHOT300/DSHOT600 high-speed digital protocols, it achieves ultra-low throttle signal latency, responsive power output and delicate controllable throttle linearity. With 50A continuous output per channel and abundant peak power headroom, it can stably drive mainstream brushless motors such as 2306, 2507 and 2807 specifications, fully meeting various power demands of 7/8 inch aircraft.
4. Wide 2-6S Voltage Support for Full Scenario Coverage
It supports a wide input range from 2S to 6S LiPo, suitable for both low-voltage configurations of lightweight practice drones and high-power demands of high-voltage long-range and aggressive freestyle flight. It flexibly adapts to 7/8 inch aircraft with different configurations, covering various flight scenarios such as daily practice, racing competitions, freestyle aerobatics and medium-range long-distance flight.
5. Standardized Stack Design for Easy Installation & Strong Anti-Interference
It adopts industry-standard mounting holes, with deeply pre-matched flight controller and ESC in hardware and firmware, eliminating the tedious steps of self-selection and compatibility debugging. The integrated internal wiring design greatly reduces redundant external wiring, effectively reduces electromagnetic interference, and improves system operation stability under heavy load conditions. Perfectly compatible with mainstream 7/8 inch FPV drone frames, it is convenient for both new drone building and existing power system upgrades.
