SimonK 30A Brushless ESC

A staple for custom quadcopters and fixed-wing RC planes, the 30A SimonK Brushless ESC provides stable motor control for entry-level builds and DIY projects. Pre-flashed with SimonK firmware, it delivers smooth throttle resolution and fast refresh rates suited for 450-class drones or standard RC aircraft.

Key features

• Pre-loaded with SimonK firmware for rapid multirotor throttle response
• Integrated 5V/3A battery eliminator circuit (BEC) to directly power a flight controller and receiver
• Handles 30A continuous current and up to 40A bursts
• No low-voltage or over-temperature cut-off, so the motor is never shut down mid-flight; monitor battery voltage through the flight controller instead
• Backward-polarity protection on the battery and 5V receiver line, so a reversed connection won't damage the motor controller
• 16KHz motor switching frequency for a quiet, responsive throttle feel

Specifications

• Continuous current: 30 A
• Burst current: 40 A (10s)
• Input voltage: 2-3S LiPo
• BEC output: 5V/3A (linear)
• Firmware: SimonK
• Throttle response rate: over 490 Hz, unbuffered input
• Dimensions: 50 x 23 x 8 mm
• Weight: 25 g

Pair this ESC with 2212 or 2208 brushless motors on 450, F650 or X525-class quadcopter frames, or use it on fixed-wing foam boards and high-speed RC cars. The integrated BEC simplifies wiring by removing the need for an external step-down voltage regulator for your 5V electronics.
