Key advantages of the engine:

• High KV value of 4300 for extreme speed

• Compact size for agile racing drones

• Powerful traction for confident acceleration and maneuvering

• Quality bearings for smooth operation

• Compatible with 2-4S batteries

This engine is made for real racers. It will turn your drone into a high-speed projectile. You will feel an instant response to commands. Every flight will be filled with adrenaline.

Operating principle and technical characteristics

The motor converts electrical energy into mechanical rotation. The stroke controller supplies current to the three phases of the stator winding. A powerful rotating magnetic field is created. It interacts with the neodymium rotor magnets. The engine shaft begins to spin rapidly.

The rated voltage is 7.4-14.8V (2-4S). This is the optimal range for racing drones. You'll get great performance on the 3S. Powerful 4S batteries will unlock your full potential.

The value of 4300 KV guarantees high speeds. This ensures maximum speed and acceleration. You will have an advantage at the start. The motor is efficient with 3-4" propellers.

The case has a diameter of 24mm and a height of 40mm. These dimensions are ideal for racing builds. The motor will not weigh down the structure. At the same time, it will provide all the necessary power.

The shaft is made of durable hardened steel. It securely locks the propellers at maximum speed. This guarantees stability in extreme conditions. You can be sure of safety.

Reliability for the race track

The manufacturer uses high-quality Japanese bearings. They provide smooth rotation with minimal losses. This increases the responsiveness and service life of the motor. Your drone will operate stably.

Efficient design provides excellent cooling. The housing actively dissipates heat from the stator. This prevents overheating during intense racing. The motor maintains stable performance.

Copper winding reduces electrical resistance. This increases the overall efficiency of the system. You get more power for the same consumption. Battery energy is used rationally.

The engine is compatible with popular frames and mounts. Its installation will not cause any difficulties. You quickly integrate it into the powertrain. The first race will be coming soon.
