Description

The Surpass Hobby Rocket 4076 motor is a high-performance, sensorless brushless unit designed for demanding aerial and terrestrial applications. Its 4-pole internal design and 1350KV rating prioritize torque over extreme speed, making it ideal for heavy-lift UAVs, large FPV drones, and high-power RC cars where consistent power delivery under load is critical. The motor is engineered to handle input voltages up to 28V (6S LiPo) and continuous currents up to 100A.

Constructed with oversized ABEC-rated bearings and a precision-balanced rotor, the 4076 ensures smooth operation at high rotational speeds while minimizing mechanical wear. The high-purity copper windings enhance electrical conductivity and thermal dissipation, allowing the motor to sustain peak performance in extended flight or run sessions. The robust 5.0mm output shaft and multi-bolt mounting pattern provide a secure, reliable mechanical interface for a wide range of propulsion systems.

Key Features

  • High-Torque 1350KV Design: Optimized for powerful thrust and efficient operation on 4S to 6S LiPo battery packs.
  • 5.0mm Hardened Steel Shaft: Provides superior strength and resistance to bending under high mechanical loads.
  • Precision-Balanced Rotor Assembly: Reduces vibration for smoother flight characteristics and extended bearing life.
  • High-Purity Copper Windings: Maximizes electrical efficiency, reduces resistance heat, and improves power density.
  • Oversized ABEC-Rated Bearings: Support high RPM operation with minimal friction and enhanced long-term reliability.
  • Universal Multi-Mount System: Features mounting holes compatible with both M3 and M4 hardware for flexible installation.
  • Robust Sensorless Operation: Eliminates hall sensors for a simpler, more durable design suitable for harsh environments.
  • High-Current Capability: Rated for continuous currents up to 100A, supporting aggressive throttle demands.

Applications

  • Heavy-lift multirotor drones and industrial UAVs requiring high torque on 6S power systems.
  • Large-scale FPV freestyle and long-range drones (7-inch and above) where efficient cruise performance is key.
  • High-power 1/8th scale RC buggies, truggies, and monster trucks.
  • Large RC boats and marine vessels needing robust, water-resistant propulsion.
  • Custom ground robot and rover projects demanding high continuous torque and durability.

Frequently Asked Questions

What is the maximum recommended battery voltage for the Surpass Hobby Rocket 4076 1350KV motor?

The motor is rated for a maximum working voltage of less than 28V. This corresponds to a 6S LiPo battery pack at full charge (4.2V per cell, totaling 25.2V), which is the standard and recommended maximum input. Operating within this 4S to 6S LiPo range ensures optimal performance and longevity.

What size propellers or pinions are suitable for this 1350KV motor on a drone?

For multirotor use, this 1350KV motor is best paired with larger, higher-pitch propellers (typically 15-18 inches in diameter) on heavy-lift frames. The low KV rating provides high torque, making it efficient for lifting heavy payloads at moderate RPMs rather than high-speed racing. Always use a current-limited ESC and perform ground tests to verify amp draw with your specific propeller choice.

Does this motor include mounting hardware, and what screw sizes does it accept?

The motor itself does not include mounting screws. It features a universal multi-mounting hole pattern that is compatible with both M3 and M4 screws. You must source the appropriate length screws based on your motor mount or frame thickness to securely attach the motor.
