at only 36.4g, the F80 PRO is about 10gr lighter than old F80, light enough 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.
