Coming in at only 31g, including wires, the F40 PRO II is very light for the power it can dish out. Another amazing feature are the high temperature silver core windings. These windings are able to withstand much higher temperatures than conventional windings. Additionally, the top of the stator has an anti-slip design that keeps your props stable during high intensity flights.
Note: This motor has no screw thread on the shaft, it will only work with POPO compatible props.
