style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I tried to research this on my own
without rehashing servo talk on the list, but I couldn’t find an answer that
satisfied my curiosity.<SPAN style="mso-spacerun: yes"> </SPAN>I will
outline my research first so that you may better help me out.<SPAN
style="mso-spacerun: yes"> </SPAN>I want to put new servos in my Used
Summit III, it has 148’s in it now and I think it flies great, no problem with
torque, and there isn’t a centering problem between days and flights.<SPAN
style="mso-spacerun: yes"> </SPAN>But, I am always hearing that better
servos will make you fly better.<SPAN style="mso-spacerun: yes">
</SPAN>And I want to be a better flier.<SPAN style="mso-spacerun: yes">
</SPAN>So, I have spent the last three weeks researching servos.<SPAN
style="mso-spacerun: yes"> </SPAN>This research must be one of those
instances when you are confused because you are paying attention.<SPAN
style="mso-spacerun: yes"> </SPAN>I want is spend less than $180, $25 -
$40 per servo and 40oz ok ailerons, 60oz rudder and elevator.<SPAN
style="mso-spacerun: yes"> </SPAN>Here is how it breaks down in my mind
from the research.<SPAN style="mso-spacerun: yes">

there isn’t really much information.<SPAN style="mso-spacerun: yes">

power than a 3-pole, I am thinking these might work for me so please try and
sell me on the coreless. <o:p></o:p></SPAN></FONT></P>

different armature system without poles that allows for better centering and a
lighter core.<SPAN style="mso-spacerun: yes"> </SPAN>Most of the low end
coreless seem like they are slower than a 3-pole.<SPAN
style="mso-spacerun: yes"> </SPAN>I am starting to thing that the
standard specs for speed are misleading. If the coreless motor is lighter and
accelerates more quickly than a 3-pole why does a $30 coreless post the same
specs as $9 el cheapo?<o:p></o:p></SPAN></FONT></P>

confused, change all of the above to digitals.<SPAN

centering and position location at 3 times the rate previously to a 3-pole
motor, why wouldn’t I want to buy it?<SPAN style="mso-spacerun: yes">
</SPAN>It should center fine because with a digital servo centering is
powered. <o:p></o:p></SPAN></FONT></P>

asking is for someone to explain why money spent on servos is valid.<SPAN

weekend after all this research and I couldn’t figure out how it could be
better. <o:p></o:p></SPAN></FONT></P>
