set-up may interest some. I have been using a Kokam 2 cell, 1500maH
Li-PO pack in my Synergy for over 12 months now ( same pack)-I'll check my
logs for flts/cycles. Sofar so good.</FONT></SPAN></DIV>

<DIV><SPAN class=580442401-14022006><FONT face="Comic Sans MS" color=#0000ff>I
regularly jam about 1300-1400 mAh into it. It has held that for the last 10
months, so it seems that all is well and on par with what is expected. I do
monitor it fairly closely and if there is degradation, I'll pull her out. I use
the Schulze 6-330d as a charger, Version 8.??</FONT></SPAN></DIV>
<DIV><SPAN class=580442401-14022006><FONT face="Comic Sans MS"
color=#0000ff>I make my own regulator, using the micrel chip-but I mount a
heatsink to it. I also use the big JR switch( which I modify) in
conjunction with the regulator. The beauty of the JR switch is that it has a
little window on there to DSC with. It makes a very tidy, regulator/switch set
up without a million leads everywhere.</FONT></SPAN></DIV>

<DIV><SPAN class=580442401-14022006><FONT face="Comic Sans MS" color=#0000ff>The
pack is mounted in that Du-bro R/C foam and is velcro'd down. I also use the
Deans mini connectors between pack and regulator input.</FONT></SPAN></DIV>

far so good-touch wood...or should that be touch 'composite'

pack is up to the current consumption your servos will dish out! If you
figure each digital servo can draw more than 3A, that is 18A out of the
pack. This is only momentary, but some of these smaller packs can be
damaged but the high current spikes. Maybe you want to try a couple of the
packs in parallel? <BR><BR>Also, the Li-Poly packs are very vibration
sensitive. Make sure you shock-mount them! And you probably don't
want to use the MPI regulators unless you parallel them so they draw 3A max
each, and have plenty of airflow. <BR><BR>Good luck! I want to hear how
that Cap flies. It looks very nice. What motor are you
using?<BR><BR>Brett<BR><BR>

<DIV>Triggered by the tease I wrote on the "Smoking li-Po" I remembered that
way back I photographed Jason's Impact at the beginning of the
National's. The FAI where he won.</DIV>
<DIV> </DIV>
<DIV>In his plane I saw a small (900 mAh) Li-Poly that he was using to work
the radio. I am/was not sure if the electric community were still doing this,
or if they had passed on the tip.</DIV>
<DIV> </DIV>
<DIV>I know that a separate battery has saved quite a few electric
pattern panes already. You tend not to hear about the catastrophic motor/Li-Po
failures from the sponsored guys. So for what it's worth here it is.</DIV>
<DIV> </DIV>
<DIV>Also, I am running one of these 2-cell 7.4V packs in a six digital servo
Great Planes 79" CAP 232. Still measuring the consumption. </DIV>
<DIV> </DIV>
<DIV>The pack weighs 1.33 oz BTW</DIV>
