Description

The Rocket 2948 brushless motor from Surpass Hobby is engineered for the specific demands of high-performance RC boating. Its 4800KV rating and 4-pole design deliver exceptional RPM for speed-focused applications, while the delta winding configuration provides a robust electrical foundation capable of handling high current loads up to 116A.

Constructed with a precision-balanced bell and a durable 3.175mm shaft, this motor is built to withstand the vibrations and cooling challenges of marine environments. The included 4mm gold bullet connectors ensure a secure, low-resistance link to compatible ESCs, completing a power system designed for reliability and top-end speed.

Key Features

  • High-KV Performance: 4800KV rating delivers high rotational speed ideal for 2S-3S LiPo setups in lightweight, high-speed boat hulls.
  • Robust Mechanical Design: Features a 4-pole internal rotor and a hardened 3.175mm shaft for durability under high torque loads.
  • Efficient Delta Winding: Delta-terminated windings provide a robust electrical configuration suited for high-current, high-RPM operation.
  • High Current Capability: Rated for a maximum current of 116A, supporting powerful ESCs and aggressive throttle punches.
  • Precision-Balanced Rotor: Dynamically balanced bell reduces vibration for smoother operation and extended bearing life.
  • Marine-Optimized Build: Construction and sealing are tailored to handle the splashes and cooling demands of RC boat use.

Applications

  • High-speed deep-V and catamaran hull RC boats running on 2S or 3S LiPo batteries.
  • Competition-level RC boat racing where maximum straight-line speed is critical.
  • Lightweight, agile RC boat builds requiring a high-KV, high-power-density motor.
  • Marine R/C applications where a 3.175mm shaft diameter is standard for direct drive or geared systems.

Frequently Asked Questions

What is the recommended battery voltage (LiPo cell count) for the Rocket 2948 4800KV motor?

The Rocket 2948 is optimized for 2S (7.4V) to 3S (11.1V) LiPo battery setups. Its 8V maximum voltage specification indicates that sustained operation at 3S requires careful throttle management and adequate cooling to prevent overheating. For best performance and longevity, pairing it with a high-current ESC rated for at least 120A is advised.

What type of connector does this motor use, and is it compatible with standard RC boat ESCs?

This motor comes pre-soldered with 4mm gold bullet connectors. These are a standard size for high-current RC applications. You will need an Electronic Speed Controller (ESC) with matching 4mm female bullet connectors or be prepared to solder on compatible connectors to ensure a secure, low-resistance connection.

Can the Rocket 2948 motor be used in drone or multirotor applications?

No, the Rocket 2948 is specifically engineered for RC marine use. Its extremely high 4800KV rating, delta winding, and thermal design are tailored for the cooling and load profile of propeller-driven boats. Using it in a multirotor would likely result in inefficient operation, rapid overheating, and incompatibility with standard drone ESCs and propellers.
