The super performance and small size of the E-flite 420BL ducted fan motor make it a great match for single- and multi-ducted fan models. The high RPM per volt (3800Kv) design allows for high RPM capability on most 66mm fan units.

WARNING: Operating the motor outside of the specifications listed above can either damage the motor, battery or esc. It is important that these components are set up properly. Failure to do so can void the warranty. It is strongly encouraged to use a Watt Meter to test the watt and amp performance when setting up a new system. If the output is above the factory recommended specs, then it needs to be adjusted by the esc. The timing and throttle settings on the esc can help to set the appropriate levels.
