• Robust design with quality bearings.

• Compatible with popular 7-9" screws.

This engine will provide a reliable foundation for your power plant. It will ensure smooth and predictable operation of the drone. You will be able to confidently perform various maneuvers at high speed. Trust the proven balance of power and control.

Operating principle and technical characteristics

The motor converts electrical energy into mechanical rotation. The stroke controller supplies three-phase current to the stator windings. A powerful rotating magnetic field is created inside the housing. It interacts with strong neodymium rotor magnets. The engine shaft begins to spin rapidly.

The rated voltage for this model is 11.1-14.8V (3-4S). This is the optimal range for high-speed flights. You will get excellent performance on 3S batteries. Powerful 4S batteries will unlock the full potential of the motor for racing.

A value of 4250 KV indicates very high rpm. This guarantees maximum speed and sharp acceleration. You will gain an advantage in racing on the straights. The motor works effectively with 7-9 inch propellers.

The motor housing measures 42mm in diameter. The length of the entire engine is 50mm. This design provides excellent power reserves. At the same time, the motor remains compact enough for most projects.

The motor shaft is made of high-strength hardened steel with a diameter of 5 mm. It securely locks the propellers at maximum speed. This guarantees stable operation in extreme conditions. You can be confident in flight safety.

Reliability for intensive use

The manufacturer uses high-quality ball bearings for smooth operation. They minimize friction and mechanical energy loss. This directly affects the responsiveness and resource of the motor. Your drone will perform consistently for many flights.

Efficient design provides excellent cooling. The aluminum housing actively dissipates heat from the stator. This prevents the winding from overheating during prolonged operation. The motor maintains stable performance in any conditions.

High quality copper winding reduces electrical resistance. This improves the overall efficiency of the power plant. You get more power for the same current consumption. Battery energy is used as efficiently as possible.

The engine is compatible with popular frames and mounts. Its installation will not cause any difficulties for users. You quickly integrate it into your powertrain. The first flight will be very soon.
