Why Choose This?
- Proven BLHeli Firmware: Unlike generic no-name ESCs that stutter on startup, BLHeli firmware ensures ultra-smooth motor response, active braking, and configurable parameters for reliable operation every time.
- Fully Programmable: Customize timing, brake strength, startup power, and throttle range through BLHeli Suite software or a standard servo tester - giving you granular control over motor behavior for any application.
- Bengaluru-Based Support: Get fast shipping across India, genuine warranty coverage, and hands-on technical guidance from The Engineer Store's team - no waiting weeks for overseas replacements.
Project Ideas
- FPV Racing Quadcopter: Build a lightweight 250-class racing drone with four 30A ESCs for aggressive throttle response and rapid directional changes during high-speed flights.
- Fixed-Wing RC Aircraft: Power a brushless outrunner motor on a trainer or sport plane with smooth throttle transitions for controlled takeoffs and landings.
- Autonomous Rover: Drive brushless hub motors on a ground robot platform, leveraging BLHeli's programmable braking and throttle curves for precise speed regulation.
What's in the Box
- 1x 30A BLHeli Brushless ESC
- Pre-soldered bullet connectors (3.5mm) for motor leads
- JST power input leads
- Servo connector cable for signal/BEC output
- Heat shrink tubing
Frequently Asked Questions
Can I use this ESC with a 4S LiPo battery?
Yes. This ESC supports 2S to 4S LiPo batteries, operating across a 7.4V to 14.8V input range. Ensure your motor's KV rating is appropriate for the voltage you plan to use.
How do I program the BLHeli settings?
You can connect the ESC to a computer via a USB linker or Arduino-based passthrough and use BLHeli Suite software. Alternatively, program basic settings using your RC transmitter's throttle stick or a standalone servo tester.
Is the BEC output sufficient to power a flight controller?
Yes. The built-in 5V/3A linear BEC can power a flight controller, receiver, and a few servos. For setups requiring more current, consider using an external BEC.
Will this work with sensored brushless motors?
No. This ESC is designed for sensorless brushless motors only. It does not have sensor wire inputs for hall-effect feedback.
What is the maximum motor size recommended for 30A?
For quadcopter builds, motors up to 2212 or 2306 size pair well at 3S-4S. Always check your motor's current draw at full throttle with your chosen propeller to stay within the 30A continuous rating.
Does The Engineer Store provide warranty on this ESC?
Yes. This ESC ships from our Bengaluru warehouse with warranty coverage. If you experience any defects, our support team will assist with troubleshooting or replacement promptly.
