Description

The Rocket 3670 brushless motor from Surpass Hobby is engineered for demanding RC boat applications where high power and reliability are paramount. Its 4-pole internal rotor design and 1850 KV rating provide a potent combination of torque and RPM, ideal for propelling scale and racing boats through the water.

Constructed with high-grade materials, the motor features a precision-balanced stator and rotor assembly to minimize vibration and ensure smooth operation. The 5.0mm diameter output shaft is manufactured from hardened steel to withstand the torsional stresses of marine propulsion. The integrated thermal management design helps dissipate heat efficiently, supporting sustained high-current operation up to 70A.

Key Features

  • High-Power 4-Pole Design: Delivers exceptional torque and RPM for thrilling acceleration and top-speed performance in RC boats.
  • Durable 5.0mm Output Shaft: Hardened steel construction provides superior strength and resistance to bending under high thrust loads.
  • Optimized Thermal Performance: Engineered stator and housing promote efficient heat dissipation for reliable operation during extended runs.
  • Precision WYE Windings: Hand-wound coils ensure consistent performance, smooth throttle response, and high power efficiency.
  • High-Current Ready: Rated for continuous 70A operation with a 23V (6S) maximum, compatible with powerful marine ESCs.
  • Gold-Plated Connectors: Includes 4mm banana plugs for low-resistance, high-reliability power connections.

Applications

  • High-speed brushless RC racing boats and catamarans.
  • Scale model warship and deep-V hull performance upgrades.
  • Heavy-duty RC tugboats and offshore rescue boat models requiring high torque.
  • Custom marine UAV (Unmanned Surface Vehicle) propulsion systems.

Frequently Asked Questions

What is the maximum recommended LiPo battery configuration for this Rocket 3670 motor?

The motor is rated for a maximum voltage of 23V, which corresponds to a 6S LiPo battery (25.2V fully charged). For optimal performance and longevity, operation within a 4S to 6S LiPo range (14.8V to 22.2V nominal) is recommended, paired with a compatible marine ESC.

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

You will need a high-current, waterproof marine ESC rated for at least 70A continuous current and compatible with 4-6S LiPo batteries. Ensure the ESC firmware supports sensorless brushless motors and is programmed for boat use to provide proper low-speed startup and reverse functionality.

Is the 5.0mm shaft compatible with standard RC boat propellers and couplings?

Yes, the 5.0mm (M5) shaft diameter is a common standard for medium to large RC boat propellers. You will need a propeller with a 5mm bore or use a reducer bushing. Ensure your drive dog, coupling, or flex shaft is also machined for a 5mm motor shaft.
