[NSRCA-discussion] Electric Pattern

As for the Axi, one of the 5320's would be the equivalent. A good way to tell would be to goto the motor finder at the axi website http://www.modelmotors.cz  Scroll to the bottom.. You can also browse the motors and it will show something like this with each motor. 

        Specification    No. of cells  6 Li-Poly    RPM/V  370 RMP/V    Max. efficiency  93%    Max. efficiency current  25 - 55 A (>85%)    No load current / 10 V  1,4 A    Current capacity  78 A/20 s    Internal Resistance  23 mohm    Dimensions (diameter. x lenght)  63x54 mm    Shaft diameter  8 mm    Weight with cables  495 g        No. of Lipol  Properler  RPM  Voltage [V]  Current [A]  Power [W]  Efficiency [%]    6s  APC-E 16"x8"  6900  21,6  46  994  85    6s  APC-E 16"x10"  6800  21,6  48  1037  85    6s  APC-E 17"x10"  6600  21,6  56  1210  83    6s  APC-E 18"x8"  6550  21,6  58,5  1264  83    6s  APC-E 18"x10"  6350  21,6  69  1490  80    6s  APC-E 18"x12"  6200  21,6  78  1685  77          

  Recommended setups for AXI 5320/18 GOLD LINE  

                          7000  247  6s  78A/20s  90A  18"x10"      5500  194  6s  78A/20s  90A  18"x12"      4300  152  6s  78A/20s  90A  20"x8"        18 -22 ccm / .91-1.2 -2stroke .1.2-1.4 -4stroke 30 - 40 ccm/2.1 - 2.4 gasoline

  It gives you a good idea, but you can also call Tom Messer at Blackbird Rc.. He has direct knowledge and testing of the 5320's in 2m pattern planes among others.. 

  As for your true or false, well my take is true depending on where you fly and in what conditions. You want more than less for sure or you will be unhappy. You don't want unneeded weight though just for more power. Defeats the purpose..

  I too, am struggling to understand how to select appropriate power for a given airplane.

  The specs for the ElectriFly 110 call for up to a 15 pound airplane, It sounds like a lot of Watts for an 8 pounder.
  A Phoenix 80 controller also sounds like a lot of over kill. Can I assume that the electrics can just be run at a lower power setting and less batteries without overburdening the airframe?

  Which AXI would be interchangeable with the Electrifly 110? 

  Would the Dualsky XM5060CA be an equivalent? The advertising indicates 1:1 correspondence to a YS 110.

  Is the following comment True or False?
  It seems that an over spec motor and speed control are only a financial mistake. Flying at reduced power levels is not a technical flaw and in fact may provide a more reliable power setup.

    Jay,

  Lots of power setups available.  It all depends on how much you want to put in.

  Hacker A50,  E-Flite 110, Axi,  BPHobbies,  Welgard, Dualsky, Neu, Hyperion, etc.

  For a reasonable price, E-Flite seems to be a good choice with Castle Phx 80 or E-Flite 60 may also work.  I went with E-Flite 110 for Inspire 90 because I couldn't install the YS110 on it.  
  Hacker, Axi are very good, but I was told these make a little noise during the run.  Not sure what that noise is.  
  Hyperion runs really good too.
  I can look up if I have spec on Focus 110.
