Looks good Eric! I just worried when you mentioned using the smaller packs. <br><br><div><span class="gmail_quote">On 2/13/06, <b class="gmail_sendername">Grow Pattern</b> <<a href="mailto:pattern4u@comcast.net">pattern4u@comcast.net

<div><font face="Arial" size="2">I put meters between the battery and the
servos. I never saw much over 500 ma even when I loaded up multiple servos.
The battery used up about 40% of its "safe" capacity in three flights. I'm
looking at the 2100 mAh packs.</font></div>

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>
