     volts) provides flight performance similar to a .55 glow engine.  We 
     find that 5000mAh LiPo packs provide between 10 to 15 minutes of 
     flight  time,  depending  on  propeller  selection  and  other  factors 
     (quality of pack, throttle management, outside  temperature,  etc.). 
     CAUTION: You must match your propeller size  to the cell  count  of 
     your LiPo pack, to avoid drawing too many amps and damaging your 
     ESC or motor.

PROPELLER FOR ELECTRIC

 

     With the Himax HC5018-530 motor  and  a 4-cell  (4S1P)  14.8v  LiPo 
     pack,  we  recommend  an   APC  12x8E  (SIG Part#  APC12080E)   or 
     13x6.5E (SIG Part# APC13065E) propeller.  This size delivered  good 
     performance, very reminiscent of a 2-stroke .46 glow engine.  For a 
     starting prop we recommend the APC 12x8E. Other brand propellers 

      of same size and similar design can also be used.  NOTE:  Your results 
      may vary due to other factors – the  specs  of  your  individual  motor 
      and battery pack, etc.  You may  need to  experiment  with  different  
      props to find your best combination. 

     With the Himax HC5018-530  motor  and a  5-cel l (5S1P)  18.5v  LiPo 
     pack, we recommend an APC 14x8.5E propeller.  This size delivered 
     good performance, very reminiscent of a  2-stroke  .55  glow  engine. 
     Other brand propellers of same size and  similar design can also  be 
     used.

BATTERY CHARGER

 

      FOR SAFETY AS WELL AS PERFORMANCE,  CHARGE  LIPO  BATTERIES 
      ONLY WITH A LIPO BATTERY CHARGER!   
      In addition to providing the critical charging profile needed to safely 
      charge  LiPo  batteries,  a  LiPo   battery  charger  also   includes   the 
      capability of "balancing" the available voltage in the  cells,  ensuring 
      that the battery pack is at peak  capacity at  the  end  of  the  charge 
      cycle.  This translates to better flight times  and  a  longer  life  from 
      the battery pack.
