Product overview
The CKESC FT 130A from Nanchang ChangKong Technology is a fixed-wing electronic speed controller for propulsion control and regulated auxiliary power. Its physical integration envelope is 92 × 40.4 × 25.5 mm, with a weight of 171 g including wiring. The electrical architecture combines low-resistance MOS devices, a 7.4 V, 10 A switching step-down BEC, shielded signal wiring and optically isolated signal input and output interfaces. Software sets motor rotation direction, while serial output supplies operating and diagnostic data.
The nominal specification is 130A 6~14S, while the continuous operating-current specification is 100 A with specified cooling; momentary operation reaches 180 A for less than three seconds. Default throttle response is 100 ms and can be customized. The 0–100% response figure of 0.6 seconds applies to some propulsion configurations. Protection functions address excessive voltage, temperature, current and motor load, unsuccessful starts, stalls and signal loss. Low-voltage protection is disabled by default, and a stall at high throttle can damage the controller.
