125A 3-8S SBEC ZTW Skyhawk Brushless ESC Fixed Wing UAV VTOL RC Helicopter ESC

Opens the 3-8S Skyhawk Line

The 125A is the entry point into Skyhawk's higher-voltage 3-8S bracket, extending the series beyond the 3-6S models to suit larger fixed-wing UAVs and heavier multirotor platforms that need higher pack voltage for more efficient power delivery.

125A Continuous / 140A Burst Current

Running near the top of its voltage bracket, the 125A still holds useful burst headroom for throttle transients and payload changes during sustained high-power, long-endurance flying.

Shares Its Footprint with the 155A

At 171g and 87×40×32mm, the 125A uses the identical housing as the higher-current 155A — a useful option for OEMs and integrators who want to design one ESC bay and offer customers a choice of current rating.

10-Gauge Wiring for High-Voltage Loads

Heavier 10-gauge power and motor wiring supports the higher continuous current and pack voltage of 3-8S operation with lower resistive loss than the 3-6S Skyhawk models.

Adjustable Cutoff Timing and Constant-Speed Mode

The same manually adjustable cutoff/restart timer and precision speed-governing algorithm carry over from the rest of the line, giving larger platforms the same crash-reducing safeguards and flight stability as smaller Skyhawk models.

10A Adjustable SBEC

Switchable 6.0V/7.4V/8.4V output at up to 10A powers a flight controller and full servo or actuator set on large-frame UAV and multirotor platforms without a separate UBEC.

Full Protection, Programming, and Data Feedback

Start-up, over-temperature, phase-loss, signal-loss, low-voltage, and over-current protection are standard, configurable via the LCD Program Card G2 or Bluetooth app, with real-time telemetry on current, voltage, temperature, RPM, and throttle status.
