<DIV>Yeah I didn't want to sound like an ad but I guess if you
look at it as a "safety" issue it's OK to point out the differences in
some of the regulators we use in our airplanes. The Tech Aero regulators
can be left connected directly to the battery 9no in-line switch
required) for a reasonable amount of time (at least a few weeks) without
any harm to the battery because they draw almost NO current when they're
"off". Not all regulators are like this.<BR>That being said,
if you're going to lay up your airplane for an extended period of time
it's important to disconnect the battery no matter what brand of
regulator you're using. <SPAN>LiPOs</SPAN> aren't too happy about being
discharged to 0V!</DIV>

John's ethics wouldn't let him send this to the list--but this is the
kind of stuff that is helpful--probably would have saved a 40.00
battery--and maybe my house--since the reg was plugged up <BR>while
Pam and I participated in a seminar for a few
days. One of those deals where I sort of pushed to get it
in the air b/4 leaving town, flew it the nite b/4, put it up--and
didn't think about it until I got back with time to run out to the
field. Battery had puffed and was 'loose'--I had no clue as to
why--except I convinced myself I MUST have left it on--or hit the
switch when I put it up. Uh, no...<BR> <BR>RS<BR><BR><BR>

<DIV>You can leave a Tech Aero regulator connected directly to
the battery for a LONG time before the battery discharges to an
unsafe level. Ed and I designed them with a very low
quiescent current draw just for that reason. We also have a
fail-safe switch arrangement on our regulators. If the switch
fails, the regulator (and your airplane) stays ON. If you put a
mechanical switch in-line between the battery and the regulator,
you could experience loss of power if the switch fails (and they
do).</DIV>

<DIV>BTW - I use the Radio South meter too. It's not
complicated to build one of these yourself but why bother? The
Radio south meter is reasonable and it works every time.</DIV>

Bought the set-up from Brian(Tanic). After I took my
completely shot 1500s back to him after they wouldn't hold a
charge--he asked " You DID separate the regulator from the
battery--didn't you--like I told you?!!!" "No", I said
sheepishly.... The regs evidently draw a tiny amount
when hooked up.<BR>I'm going to call Tony--that's
<EM>exactly</EM> what I was looking
for!<BR> <BR>Thanks,<BR> <BR>Richard<BR><BR>>
