Product overview
The CKESC FLY 50A from Nanchang ChangKong Technology Co., Ltd is an electronic speed controller for fixed-wing propulsion. Its 62 × 25 × 10mm body and 26.7g weight, including wiring, define its physical integration requirements. The electrical configuration combines a 3~4S input with a switching step-down BEC rated at 5V 3A. Power filtering uses a Rubycon electrolytic capacitor and high-capacitance ceramic capacitors, while synchronous rectification is enabled by default. The controller also incorporates industrial-grade firmware, adaptive operating parameters and dual temperature monitoring.
Current capability depends on cooling and operating duration: maximum continuous current is 50A under specific cooling conditions, with 55A specified for 30 seconds and 60A for two seconds. Throttle travel spans 1000~2000us. Standard and high-speed versions have separate rotational-speed specifications for 2-, 12- and 14-pole motors. Protection functions cover unsuccessful startup, stalls, overload, low voltage, overheating and signal loss. A high-throttle stall can still damage the controller, and temperatures above 115°C trigger a gradual power reduction that can reach 40% of full-throttle power.
