GEPRC SPEEDX2 1404 Motor

The GEPRC SPEEDX2 1404 is a high-efficiency brushless motor engineered for sub-250g FPV builds — 2.5-inch cinewhoops, lightweight toothpicks, and 4-inch micro long-range cruisers — offered here in 3000KV, 3850KV and 4600KV winds for 3S-4S LiPo power.

Key features

• High-torque rotor: N52H curved arc magnets in a 9N12P stator deliver rapid, linear throttle response.
• Durable construction: precision-machined housing with quality bearings keeps weight to 10.5g including the silicone lead wire.
• Universal micro mounting: a 9x9mm (M2) base pattern and a 1.5mm shaft fit modern micro frames and propellers.
• Large cooling cutouts across the bell improve airflow and hold stator temperatures down during hard throttle punches.
