Holybro Ripper 1404 3800KV Ultralight Brushless Motor (Pack of 4)

The Ripper 1404 3800KV motor is optimized for 2.5-inch to 4-inch propellers on lightweight micro and mini quadcopter frames. For 3S setups, 3-inch bi-blade or tri-blade props provide excellent efficiency and thrust. On 4S, you can run aggressive 3-inch tri-blades or smaller 4-inch bi-blades for high-speed performance while staying within the motor's 15.85A peak current limit.

Yes, the Holybro Ripper 1404 3800KV motor is fully compatible with 4S LiPo batteries (14.8V nominal). Its electrical design and winding configuration are engineered to handle the increased voltage and RPM, delivering higher top-end thrust. Ensure your Electronic Speed Controllers (ESCs) are rated for 4S operation and can handle the increased current draw, especially when paired with aggressive propeller loads.

The Holybro Ripper 1404 motor uses the standard M2 mounting hole pattern common to micro brushless motors. The bolt circle diameter (BCD) is typically 12mm, but always verify with your specific frame's motor mounting template. The motor includes M2 mounting screws, and its compact Ø18.2mm bell diameter ensures compatibility with tight frame designs and propeller clearance.
