XXD HW30A 30A Brushless ESC with 2A BEC, 2-3S

The XXD HW30A is a single 30 A brushless ESC for 2–3S LiPo setups, a common pick for F450-class quadcopters, trainer planes and park flyers. Its built-in 2 A BEC can power the receiver and servos on a plane, or a basic flight controller and receiver on a multirotor, without a separate regulator.

Key features

• 30 A continuous, 40 A burst for under 10 seconds
• Flexible input: 2–3S LiPo or 5–12 cell NiMH/NiCd packs (5.6–16.8 V)
• Safe start: the motor will not spin up at power-on, whatever position the throttle stick is in
• Throttle calibration adapts the ESC to your transmitter's throttle travel for smooth, linear response
• Low-voltage protection with a cut-off threshold to guard the pack against over-discharge
• Supplied with bullet connectors

Pick a motor and prop whose peak draw stays under 30 A on your pack, and fit one ESC per motor: four for a quadcopter, one for a single-motor plane.
