Surpass Hobby Rocket 4076 Sensorless Brushless Motor 5.0mm Shaft 1700KV - Black

The motor is rated for a maximum working voltage of less than 23V. This makes it compatible with up to 6S LiPo battery packs (25.2V fully charged), though it is best practice to stay within the continuous voltage range of a typical 6S pack under load. Always pair it with a capable ESC rated for 6S operation.

This is a sensorless brushless motor, meaning it does not have internal hall sensors. It must be paired with a sensorless-compatible ESC. Most modern ESCs support sensorless operation, which simplifies wiring and increases reliability by eliminating a potential point of failure.

With its 1700KV rating and 5.0mm shaft, this motor is engineered for high-torque applications. It is ideal for 1/8th scale RC cars, heavy-lift multirotor drones, large FPV racing frames (7-inch+), and other platforms where moving significant mass or spinning large propellers is required. Its multi-mount system fits M3 and M4 screw patterns.

A 4-pole motor design typically offers a favorable balance of torque and RPM. Compared to 2-pole motors, it can provide smoother low-speed operation and higher torque density, which is beneficial for accelerating heavy loads. This makes the 4076 particularly effective in applications requiring strong initial thrust or pulling power.
