BrotherHobby VY 1507 1550KV Motor

The BrotherHobby VY 1507 1550KV is an efficiency-focused micro brushless motor built for 6S 4-inch long-range cruisers, heavy 3-inch cinewhoops, and ultralight 5-inch toothpick drones. Tuned to an unusually low 1550KV, it is engineered for high-voltage setups where maximizing flight time and low-end throttle resolution take priority over raw top speed.

Key features

• Machined from aerospace-grade 7075 aluminium alloy, providing a resilient bell and base structure without adding unnecessary bulk.

• Constructed with 0.15mm Nippon Steel laminations and high-temperature N52H arc magnets for consistent, efficient torque delivery.

• Fitted with premium Japanese NSK bearings to minimize motor resonance and ensure cleaner flight controller gyro data.

• Features a lightweight, hollow 5mm titanium alloy prop shaft, allowing standard locknut compatibility with M5-hub 3-inch to 5-inch propellers.
