Description

The EX1202.5 KV6400 brushless motor is a precision-engineered component designed for the demanding requirements of micro and whoop-style FPV drones. Its 9N12P magnetic configuration and optimized stator geometry ensure minimal vibration and high efficiency, translating to longer flight times and smoother video footage.

Constructed with durable materials, this motor maintains reliable performance even under the thermal stress of aggressive freestyle maneuvers. The compact 15mm x 15mm mounting footprint and 1.5mm shaft make it a direct-fit upgrade for popular lightweight frames, offering pilots a high thrust-to-weight ratio without compromising on flight characteristics.

Key Features

  • High-performance 9N12P brushless motor configuration for smooth operation.
  • Ultra-lightweight construction at just 4.4 grams per motor.
  • Optimized for 2S to 3S LiPo input voltage, offering flexible power options.
  • Precision-machined 1.5mm output shaft ensures secure propeller grip.
  • Durable 12mm diameter x 2.5mm height stator for reliable power generation.
  • Specifically tuned for lightweight builds such as the HappyModel Crux3.
  • Compact motor dimensions (approx. 15mm x 15mm) for tight frame integration.

Applications

  • Ultralight 2S-3S toothpick and micro freestyle FPV drones.
  • Direct upgrade or replacement for HappyModel Crux3 and similar lightweight builds.
  • Compact CineWhoop platforms requiring smooth, efficient power for cinematic footage.
  • Agile indoor racing drones where minimal weight and responsive throttle are critical.

Frequently Asked Questions

What is the input voltage range for the EX1202.5 KV6400 motor?

The EX1202.5 KV6400 motor is optimized for 2S to 3S LiPo batteries (7.4V to 11.1V). Operating outside this range, especially on higher cell counts like 4S, may lead to excessive heat, reduced efficiency, and potential motor failure.

What propeller size and mounting pattern does this motor use?

This motor uses a 1.5mm diameter propeller shaft, compatible with push-on props designed for micro builds. It features an M2 mounting screw pattern with an approximate 15mm x 15mm hole spacing, making it a direct fit for many lightweight micro frames like the HappyModel Crux3.

Is this motor suitable for Betaflight and BLHeli_S ESCs?

Yes, as a standard 3-wire brushless motor, it is fully compatible with all BLHeli_S, BLHeli_32, and Bluejay firmware ESCs. Ensure your ESC is rated for the current draw expected from this 6400KV motor on your chosen battery (2S or 3S) and propeller combination.
