COUNTER ROTATING RC Lander Dynamic Power Series 4S Metal Fan offers great durability with a metal fan unit that offers good performance.  This fan unit rotates the opposite direction (Clockwise/ to the right) of a traditional fan unit.  It can either be used by itself or in a twin set up with the standard 4000kv 4s DPS fan unit.

All RC Lander fans and motors are test run at the factory to ensure that they are in proper operating manner before being shipped out. The fans are put through a series of tests to ensure that they are operating as intended. Be sure to reference the instruction manual for proper motor and esc program settings.

FEATURES:

A lot of EDF units are made of plastic material which during operation creates high temperature. This results in loss of power and the possibiltiy of damage to the motor, battery or speed control. Heat sinks help, but this only offers average improvement. RC Lander Technology uses special metals to imporve dissapation of heat in their EDF units. The shroud, spinner and tail pipe are made with a special aluminum alloy that is efficient at heat dissapation. Because of this, the whole shroud acts as a heat sink, removing heat from the motor. The motor and fan unit comes assembled and balanced from the factory. A thermal grease compound is used between the motor and shroud to further help dissipate heat. This is the same compound that is used in computer processors and heat sinks. This design creates a more efficiently running motor and will provide peak performance while extending the lifespan of the motor.

Motor construction consist of a 4 pole motor giving beter performance which translates into higher rpm's and efficiency.

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.
