Hobbywing XRotor 20A Drone ESC

The Hobbywing XRotor 20A is a single-motor ESC for 330-450 class multirotor builds, running Hobbywing's own multirotor-tuned firmware for stable, responsive flight.

Key features

• 20A continuous / 30A peak (10 s) current rating on 3-4S LiPo.
• No onboard BEC, so the flight controller or a separate BEC must power the receiver and flight electronics.
• 3.5mm gold connectors on the output leads for a quick, secure motor connection.
• Compact body weighing about 14 g, keeping the build light.

Fit one ESC per motor, and confirm your flight controller's timing and signal-frequency support before wiring it in. This listing is for a single ESC, so order one per motor on a quadcopter or multirotor build. Route the output wires away from sharp frame edges to avoid chafing during flight.
