Drone ESC ZTW 85A 3-6S SBEC Brushless Drone Speed Controller

ZTW Skyhawk 85A 3-6S SBEC Brushless ESC for Fixed-Wing UAV VTOL RC Helicopter

Tops the 3-6S Skyhawk Line

The 85A is the highest-current option in the 3-6S Skyhawk range before stepping up to the 3-8S 125A model — a natural fit for higher-power fixed-wing UAVs and multirotor platforms that need sustained current without moving to a higher pack voltage.

85A Continuous / 130A Burst Current

A burst rating over 1.5x continuous output gives the 85A substantial headroom for hard throttle transients and payload changes, keeping thrust stable through demanding long-endurance or heavy-lift missions.

12-Gauge Wiring for Higher Sustained Loads

Heavier-gauge power and motor wiring than the 35A and 65A models reduces resistive losses at higher current, supporting longer mission times and harder-working motors on larger UAV and multirotor platforms.

Enhanced Cooling Architecture

An updated case design and airflow path are engineered to keep the ESC stable under extreme, sustained loads — important for the longer flight times and higher average power draw typical of survey, mapping, and light agricultural missions.

10A Adjustable SBEC

Switchable 6.0V/7.4V/8.4V output at up to 10A comfortably powers a flight controller and full servo or actuator set on larger platforms without an external UBEC, simplifying the power architecture.

Constant-Speed Governing for Payload Stability

An advanced speed-governing algorithm holds propeller RPM steady as payload or wind load changes — a genuine advantage for multirotor platforms carrying variable loads, such as spraying drones that lose weight during a mission.

Full Protection and Telemetry Suite

Start-up, over-temperature, phase-loss, signal-loss, low-voltage, and over-current protection come standard, alongside real-time current, voltage, RPM, and status feedback through the LCD card or Bluetooth app.
