Description

The Surpass Hobby 3660 ROCKET motor leverages a sensorless design to eliminate hall sensor failures, simplifying the power system while enhancing overall durability. Its robust 3660 can size houses a precision-machined rotor and high-grade ABEC bearings, engineered to handle extreme RPMs with minimal friction and vibration.

Built with waterproofing in mind, the motor’s sealed end caps and shaft seals protect the internal windings and bearings from moisture, dirt, and debris. This makes it an ideal propulsion unit for RC buggies, truggies, boats, and UAVs operating in challenging outdoor conditions where reliability is paramount.

Key Features

  • Sensorless Waterproof Design: Eliminates hall sensor complexity and provides protection against water and contaminants for extended motor life.
  • High-Purity Copper Windings: Optimized for low electrical resistance, maximizing power efficiency and thermal performance under load.
  • Precision-Balanced 4-Pole Rotor: Computer-balanced for minimal vibration, ensuring smooth operation and maximum reliability at high RPM.
  • Oversized ABEC Bearings: High-RPM rated bearings reduce rotational friction, supporting sustained high-speed performance.
  • Versatile Mounting: Universal multi-mount system compatible with M3 and M4 screws, fitting standard 1/8th scale vehicle and drone frames.
  • Gold-Plated 4.0mm Connectors: Provide a secure, low-resistance connection for consistent power delivery from the ESC.

Applications

  • High-speed 1/8th scale RC buggies, truggies, and on-road vehicles requiring robust, waterproof power.
  • RC boat and marine applications where a sealed motor is essential for operation in water.
  • Heavy-lift multirotor drones and industrial UAVs that demand high torque and reliability from a 3660-can motor.
  • Custom high-power ground vehicle projects where sensorless simplicity and durability are key.

Frequently Asked Questions

What is the maximum recommended LiPo battery configuration for this 3660 2350KV motor?

The motor is rated for a maximum working voltage of less than 21V. This makes it suitable for 4S (16.8V), 5S (21.0V), and 6S (25.2V) LiPo batteries, though operation at 6S may push the upper limit and requires careful ESC matching and thermal management. For continuous high-power use, 4S or 5S configurations are recommended.

Does this sensorless motor require a specific type of Electronic Speed Controller (ESC)?

Yes, it requires a sensorless brushless ESC. The ESC must be capable of driving a 4-pole outrunner motor and support the motor's high current draw of up to 57A. Ensure the ESC's firmware (e.g., BLHeli_S, BLHeli_32) is configured for sensorless operation and can handle the input voltage of your chosen battery pack.

Is the waterproofing sufficient for submersion, and what maintenance is required?

The waterproofing is designed to protect against splashes, rain, and wet conditions typical in off-road RC use. It is not intended for prolonged submersion. After use in wet environments, it is good practice to rinse with fresh water and dry the exterior to prevent corrosion on the shaft and connectors.

What is the compatible mounting pattern for this motor?

The motor features a universal multi-mount system with threaded holes compatible with both M3 and M4 screws. This allows it to fit a wide range of standard mounting plates on 1/8th scale RC car chassis, boat mounts, and custom drone frames without requiring an adapter.
