<DIV class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">You should not need
any kind of signal buffer. The main problem with long leads is
excessive voltage drop due to higher resistance if the wire gauge is too
light. Just use 22AWG and also avoid any tin plated connectors and you
should be fine. Braided wire can be helpful, but isn’t really necessary most
of the time. </SPAN></FONT></DIV>

<DIV class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">Re. the use of
either Lithium Ion or Lithium Polymer batteries, yes, you need a
regulator. The Jaccio works really well. I also make regulators
that are adjustable and fill a niche if you have a need for redundant
batteries and want some additional flexibility in the setup. Either
solution can work. And you are correct that a 480 mAh pack isn’t a lot
of capacity, however with a good LiPo, there ability to deliver current on
demand is more than adequate. Capacity for some number of flights is
the bigger question. </SPAN></FONT></DIV>

<DIV class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">The electric
powered pattern models use a very small amount of current in flight because
of the virtual elimination of vibration from the power plant, so you will
see guys going all weekend with a pair of 2S480 packs. I still fly
glow and use a pair of 730mAh packs.</SPAN></FONT></DIV>

<DIV>
<DIV class=MsoNormal style="MARGIN-LEFT: 0.5in"><FONT face="Times New Roman"
size=3><SPAN style="FONT-SIZE: 12pt">I used to use JR servo amplifiers on
servos to eliminate noise and ensure strong signal over a long servo lead,
especially to the back of the plane. Few of these, if any, are
available commercially now, so I assume that there is little need for them
any more? (Was never convinced they served a purpose to begin with, but I
had never built a plane without them, and never had a
problem)</SPAN></FONT></DIV></DIV>

<DIV>
<DIV class=MsoNormal style="MARGIN-LEFT: 0.5in"><FONT face="Times New Roman"
size=3><SPAN style="FONT-SIZE: 12pt">Maybe as simple an answer as "never an
issue, regardless of servo wire length".</SPAN></FONT></DIV></DIV>

<DIV>
<DIV class=MsoNormal style="MARGIN-LEFT: 0.5in"><FONT face="Times New Roman"
size=3><SPAN style="FONT-SIZE: 12pt">I used to use nothing other than large

<DIV>
<DIV class=MsoNormal style="MARGIN-LEFT: 0.5in"><FONT face="Times New Roman"
size=3><SPAN style="FONT-SIZE: 12pt">I notice that folks are now using
Thunder Power Li-Po batteries, some as small as 480mAh, and several
around 800mAh. Doesn't seem to be much capacity to run six
digitals.</SPAN></FONT></DIV></DIV>
<DIV>
<DIV class=MsoNormal style="MARGIN-LEFT: 0.5in"><FONT face="Times New Roman"
size=3><SPAN style="FONT-SIZE: 12pt">I assume there is a Jaccio regulator to
cut it down to 5V or so. Are Li-Pos reliable enough that only one cell is
used, or are some folks using a SmartFly dual battery regulator that ignores
one battery if it should fail?</SPAN></FONT></DIV></DIV>
