The Hobbywing SeaKing 120A V4 Brushless Marine Electronic Speed Controller (ESC) is designed to deliver exceptional performance for marine applications. With advanced waterproofing, built-in Bluetooth functionality, and a robust power management system, this ESC is ideal for competitive racers and RC boat enthusiasts. Engineered for reliability and convenience, it offers seamless integration with modern technology to provide a superior racing experience. Featuring an IP67 protection rating, the SeaKing 120A V4 is designed to withstand water, dust, and splashes under normal usage conditions without requiring additional waterproofing treatments. Its dual-channel water cooling system enhances heat dissipation, ensuring the ESC maintains safe operating temperatures during intense use. For added protection, the ESC includes a spark-proof circuit and capacitor overheating safeguards, extending its durability in demanding environments. The built-in Bluetooth functionality simplifies ESC programming and firmware updates. Users can connect directly to the "HW LINK V2" app on their mobile devices to adjust settings, view historical data, and monitor performance in real-time without additional hardware. The ESC's internal logging module captures up to ten minutes of operational data, enabling post-run analysis through the app for optimal tuning and maintenance. The SeaKing 120A V4 is equipped with a powerful switch-mode BEC with selectable output voltages of 6V, 7.4V, and 8.4V. This ensures compatibility with high-torque and high-voltage servos for precise and responsive control. Additionally, the Freewheeling function enhances deceleration and steering control, while the AUX external control channel allows for real-time parameter adjustments using the remote, ensuring unparalleled control during competitive races.

Features:
Experienced Installation Required
Integy products are designed for experienced RC enthusiasts. Unless included with the product itself, most of our products do not include instructions. The purchaser is responsible for any product assembly/disassembly, any set-up and adjustment, and periodic maintenance. If you need help disassembling your stock vehicle, you will need to refer to the instruction manual/exploded parts view of your particular vehicle, as provided by the manufacturer of your vehicle. If you are unable to assemble and/or install a product, please consult your local Integy dealer for assistance.
Assembly and Pre-installation Prep
All products (including hop-ups, tools, chassis and electronics) may require some prep out of the package. Some items (shocks, gearboxes, axles, etc.) are assembled for packaging purposes only, and may require standard prep before installation and usage, such as shimming for proper alignment, confirming gear mesh, checking tightness of all components and fasteners, installing your own shock oil, anti-seize, threadlock, or grease. Please be sure to apply threadlock on all metal-to-metal interfaces prior to installation; do not just install the item out of the package and assume they have been prepped correctly. Check, adjust, and set/reset all new items when taken out of the package. Some items may need final adjustment after installation.
Wheel and tire sets may be sold partially assembled for packaging purposes only and require standard wheel/tire prep before installation and usage. All wheels and tires require CA glue (if press-fit style) or separate assembly (if beadlock style) before being used. Wheels and tires are not always pre-glued from the factory (unless specified in the product name or description).
A Note About Hardware
Unless specified, not all products include hardware; if new or different-sized hardware and/or fasteners are included with the upgrade kit, those are meant to replace the factory hardware. Extra hardware, shims, or spacers may be required for some installations. Due to factory supply delays beyond our control, certain products may ship with hardware (screws, washers, etc.) that is different from what is originally shown in the website product photos. Any alternates will be compatible hardware that will not affect the functionality of the product.
1st/3rd-party Compatibility
Certain Integy-branded items replacing OEM parts may not be compatible with another Integy-branded items due to design language. Some parts may require permanent modification to the vehicle for fitment and may eliminate certain OEM features. Some items may require modification to the vehicle for proper clearance. Parts are for specified usage only. We do not guarantee compatibility with other aftermarket items.
What does "RTR" or "ARTR" Mean?
When a product is labelled RTR ("Ready To Run") it generally means that the vehicle chassis is assembled, and electronics are installed. You may still need some final items for operation (i.e. transmitter alkaline batteries, main battery pack and charger, paint for the body, etc.). When a product is labelled "ARTR" generally this means the same as "RTR" but without an included radio system and/or radio components. Please refer to the product description for additional details; no additional items are included unless specifically stated in the product description. ARTR and RTR vehicles must be prepped by the user or a knowledgeable hobbyist prior to the first drive, as some details should be checked prior to driving i.e. tires and wheels are tight, gear mesh is correct, steering servo is centered, etc.
Product Photo Accuracy
Products show in photos may be updated at the production level and replaced by updated versions; we will always ship the most recent version to the customer. Colors shown in product photos are as close to possible to the actual item; color matching between parts is not guaranteed.
