Readytosky 40A Single ESC (2-6S, 3.5mm Connectors)

The Readytosky 40A Single ESC provides straightforward power delivery for fixed-wing aircraft, 450-class multirotors, and custom DIY drone builds. Rated for up to 6S LiPo input, it handles a continuous 40A load to drive medium-to-large brushless motors. Pre-soldered with 3.5mm banana (bullet) connectors on the motor phases, it eliminates the need to solder motor wires, allowing for fast, plug-and-play swaps in the field or at the bench.

Key features

• Supports a wide 2-6S LiPo voltage range for flexible battery configurations

• Delivers 40A continuous current to handle high thrust requirements

• Pre-installed 3.5mm female bullet connectors for quick, solder-free motor connections

• Slim heat-shrink profile fits easily inside plane fuselages or mounts cleanly on multirotor arms

Specifications

• Continuous current: 40A

• Input voltage: 2-6S

• Motor connectors: 3.5mm banana/bullet

This ESC fits perfectly into budget quadcopters (like F450 or S500 frames) and RC planes requiring a standalone speed controller. Ensure your build includes a separate 5V BEC to power your receiver and servos if you are operating an OPTO setup without onboard step-down power.
