BetaFPV 1805 Brushless Motors

BETAFPV 1805 series brushless motors are available in two KV options. The 1805 2550KV motor is ideal for 4S power systems, while the 1805 1550KV motor is best suited for 6S setups. Paired with a 35A AIO Brushless FC, these motors deliver massive power for high-performance racing quadcopters. Designed for 4–5 inch frame builds, we recommend using 5125 or 5020 propellers to achieve optimal power output during FPV racing.
