ZTW Skyhawk 155A 3-8S SBEC Brushless ESC for Fixed-Wing UAV VTOL RC Helicopter
Tops the 3-8S Skyhawk Line
The 155A is the highest-current option in the 3-8S Skyhawk range before stepping up to the 6-14S HV models — the choice for large fixed-wing UAVs and heavy-lift multirotor platforms that need more continuous power without moving to a higher-voltage battery pack.
155A Continuous / 170A Burst Current
Running at the top of its voltage bracket, the 155A still delivers meaningful burst headroom for hard throttle and payload-driven load changes on large platforms under sustained high load and long mission times.
Same Compact Footprint as the 125A
Housed in the same 171g, 87×40×32mm frame as the 125A, the 155A gives builders more current in an already-proven ESC bay — no redesign needed to move up the power range for a higher-performance platform.
High-Efficiency Thermal Dissipation Structure
Side vents paired with a dedicated airflow duct push cooling air into the ESC's middle layer, not just the surface — addressing the heat buildup that fan-only designs often miss on long, high-power missions.
Constant-Speed Governing for Heavy-Lift Stability
The advanced speed-governing algorithm keeps propeller RPM stable as payload changes, a meaningful advantage for heavy-lift multirotor platforms and large fixed-wing UAVs flying long, variable-load missions.
10A Adjustable SBEC
Switchable 6.0V/7.4V/8.4V output at up to 10A reliably powers a flight controller and full servo or actuator set on large platforms without needing a separate UBEC.
Complete Protection and Telemetry
Start-up, over-temperature, phase-loss, signal-loss, low-voltage, and over-current protection are standard, with real-time current, voltage, RPM, and status data available via the LCD card or Bluetooth app.
