testing device but that is its main function . It does test the battery with no
load and with a user programmable load, it then calculates and displays the
packs internal resistance. It has programmable alarms points and two difference
voltage profiles you can configure.</FONT></SPAN></DIV>

width going to a servo from your receiver, it will drive your servo and you can
use it as a data logger.</FONT></SPAN></DIV>

<DIV dir=ltr>I do have the serial interface but haven't needed to use it since
Gordon programmed mine with what I needed at the time I purchased it.
Changing parameters in the interface is very straightforward.<BR><BR>

<DIV>I would go with Gordon Anderson's Maestro - I've been using it for a
while now and love it. I check my batteries every flight but
unfortunately that isn't a guarantee against battery failure either.
:-( I had my ProLine go in after I checked the 4 cell Nicad (5.56v and
under load of 5.01v). </DIV>

This is a habit I had early on, but 8 years in pattern and no battery

using for my new $2000+ airplane? Please let me know what you guys
