Eric,<br><br>make sure the battery 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><span class="gmail_quote">On 2/13/06, <b class="gmail_sendername">Grow Pattern</b> <<a href="mailto:pattern4u@comcast.net">

<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>
