90-120mm Set Up Guide
There are many combinations and set ups that will work for electric powered aircraft.  Here are some formulas that will make it easy for you to determine what the proper set up will be for a jet.

To calculate your fan rpm's: Take the voltage of the battery and multiply the KV of the motor = Fan RPM
                                                                   11.1v X 3600= 39,960 rpm.

To calculate what KV motor you need: Take the desired fan RPM divide it by the battery voltage= Needed Motor KV
                                                                   45,000/ 14.8v=3040kv motor.

To calculate what battery you need: Take desired fan RPM divide it by the motor kv = Battery Size
                                                                   45,000/ 3600kv=12.5v (3 cell).

To calculate approximate amps drawn: Take watts divide it by the volts = Amps
                                                                   800 watts/ 14.8v=54amps.

To calculate volts needed: Take watts divide it by the amps = volts
                                                                   450 watts/ 40amps= 11.25volts.

To calculate watts: Take amps multiply it by volts = Watts
                                                                   57amps X 14.8v= 843watts.

These are approximate numbers depending on efficiency, quality of connections, and resistance, but this guide line will help determine what set up to use with electrics.  The data below are estimations based on the above formulas and information provided by the manufacturer.  Fan Jets USA is not responsible for changes in the specifications of the motors by the manufacturer.


The following are recommended setups for edf units based on fan rpm's. The higher the fan rpm, the faster the jet.  The 90mm edf's are designed to operate from 30,000 to 47,000 rpm. Speeds vary based on the weight and aerodynamics of the jet. The 120mm edf units are designed to operate around 24,000 to 38,000 rpm. Any thing above this, may exceed the manufacturers recommendations.  Speeds vary based on the weight and aerodynamics of the jet. 

Be sure to use a watt meter when programming the power system to check watt and amp draw.  This can be limited by adjusting the throttle  epa's.  Going up in blade count will have an impact on watt and amp draw.  Generally a lower kv motor should be used on edf's that have higher blade counts.

COLOR CODE (Estimations): ORANGE= MILD SETUP (60 TO 90 MPH)
                                         
GREEN= MODERATE SETUP (90 TO 120 MPH)
                                          RED= WILD SETUP (120 PLUS MPH)
