<DIV><FONT face=Arial size=2>For pattern a good rule of thumb is 150 watts per
pound. A better rule of thumb is closer to 200 watts per pound. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It takes a lot of experimentation to find the right
combination, sometimes what looks great on paper doesn't work all that well in
application. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>What you're looking for is more than you "need".
this way when you push it in bad conditions, you don't burn it all
up.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have found some very cheap chinese motors that
work as good or better than what we can get over here from the more established
companies. Some combinations are really cool, especially in the 110 range.
You're looking for around 1600-2000 watts, motor weight about 500 grams or less,
about 250-300kv, and using 8s packs. Lethal =) And fairly
inexpensive.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Then you just have to figure out whether you want
to turn a large prop slow or a small prop fast. Somewhere in there, you hit the
magic for the particular plane. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>But if you want "established", the E flight power
110 is ok, and the Axi 4130-20 works. Don't get the -16 turn axi as it won't
handle 8 cells and won't deliver quite enough power.</FONT></DIV>

<DIV><FONT face=Arial size=2>I am not picking on Incheon here, the questions
are to all:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I too, am struggling to understand how to select
appropriate power for a given airplane.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>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.</FONT></DIV>
<DIV><FONT face=Arial size=2>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?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Which AXI would be interchangeable with the
Electrifly 110? </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Would the Dualsky XM5060CA be an equivalent? The
advertising indicates 1:1 correspondence to a YS 110.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Is the following comment True or
False?</FONT></DIV>
<DIV><FONT face=Arial size=2>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.</FONT></DIV>
