Description

The Rocket 2948 brushless motor from Surpass Hobby is engineered for the specific demands of high-performance RC boating. Its 6800 KV rating provides exceptional rotational speed on 2S to 3S LiPo battery configurations, translating to rapid acceleration and top-end velocity. The 4-pole internal design, combined with a delta winding, ensures smooth torque delivery and efficient power conversion, even under the high-load conditions typical of marine propulsion.

Constructed with a focus on durability, the motor features a precision-machined 3.175mm steel shaft and a robust housing to withstand the vibrations and cooling challenges of wet environments. With a peak current handling of 116A, it is built to manage the intense power spikes of competitive racing. The integrated 4mm gold bullet connectors facilitate a clean and reliable installation, minimizing power loss at the connection points.

Key Features

  • High-RPM Design: 6800 KV rating delivers exceptional speed for competitive RC boat racing and high-speed runs.
  • Robust Power Handling: Capable of sustaining up to 116A maximum current for intense, high-throttle operation.
  • Durable Mechanical Construction: Features a hardened 3.175mm steel shaft and a balanced rotor for longevity and reduced vibration.
  • Efficient Delta Winding: Provides a favorable balance of torque and RPM, with good thermal characteristics under load.
  • Integrated Connectors: Pre-soldered 4mm gold bullet connectors ensure a secure, low-resistance power link to compatible ESCs.
  • Precision Balanced: Dynamically balanced for smooth operation, reducing wear on bearings and improving overall system efficiency.

Applications

  • High-speed deep-V and catamaran RC race boats requiring extreme RPM.
  • Performance-focused RC scale boats and hydroplanes on 2S to 3S LiPo power.
  • Marine FPV and drone-racing boat conversions where high KV and compact size are critical.
  • Custom high-speed electric watercraft and experimental marine propulsion projects.

Frequently Asked Questions

What is the recommended battery voltage for the Rocket 2948 6800KV motor?

The Rocket 2948 is rated for a maximum voltage of 8V, which corresponds to a 2S LiPo battery (nominal 7.4V). While it may handle brief peaks on a fresh 3S pack (12.6V), continuous operation above 8V exceeds specifications and risks damaging the windings. For optimal performance and longevity, use a 2S LiPo configuration.

What type of Electronic Speed Controller (ESC) is required for this motor?

This motor requires a brushless ESC capable of handling its high current draw, up to 116A continuous. A marine-grade, waterproof ESC rated for at least 120A on 2S-3S is recommended. Ensure the ESC supports the motor's high KV and pole count, and use the provided 4mm gold bullet connectors for a secure connection.

Is the motor pre-balanced, and what maintenance does it require?

Yes, the Rocket 2948 is dynamically balanced at the factory for smooth operation. Regular maintenance should include inspecting the 3.175mm shaft for straightness, checking bearings for smooth rotation, and ensuring the bullet connectors remain tight and corrosion-free, especially after exposure to water. Applying a light corrosion inhibitor to electrical contacts is advised for marine use.
