HOBBYWING Seaking 30A V3 ESC - 30302060 Compact Marine ESC  [HW-30302060]

Compact marine ESC tuned for dependable on-water control

Built for dedicated RC boat hobbyists, this electronic speed controller delivers steady, predictable throttle response while fitting neatly into smaller hulls. It is engineered for efficient operation in boats under 45cm and focuses on reliability and clean power delivery.

Reliable protection features

The Seaking unit combines quality components with mature firmware to provide stable operation. It includes safeguards such as low-voltage cutoff, thermal protection, and signal-loss protection to help prevent damage during spirited runs.

Efficient water-cooled heat path

Heat management is handled via a copper heat-conductive cover that routes thermal energy into a CNC-machined billet aluminium water-cooled sink. The layout helps maintain safe temperatures during prolonged use.

Waterproof construction for wet conditions

The sealed design means the ESC does not require extra potting for basic water resistance, making it suitable for aggressive lake or pond use with routine maintenance.

Onboard BEC and easy programming

The internal switch-mode BEC provides a stable 6V at up to 6A to support modern servos, and a dedicated PRG/FAN port allows simple adjustments with a program box or fan accessory.

For pilots who want a compact, serviceable ESC for smaller boats, this unit balances cooling, waterproofing, and a solid safety package to keep on-water time consistent and trouble-free.
