<DIV><FONT face=Arial size=2>Hi Mike,</FONT></DIV>
<DIV><FONT face=Arial size=2>You can use Li-Poly. I feel that the Li-Ions
might be safer because of the conventional metal case and vent. The same
regulators can be used but you might need a heat sink to keep the temperature
down if you are pulling a lot of current. With 5 digitals and one analog I
have not needed a heat sink.</FONT></DIV>
<DIV><FONT face=Arial size=2>One of the great things about them is the self
discharge is very slow. I recently flew two flights one week and 4 the
next without recharging. Still had plenty left. I chose 2000 mAh
because they weren't much larger or heavier than the 1200s. Of course the
Li-Poly will be smaller and lighter.</FONT></DIV>
<DIV><FONT face=Arial size=2>I believe this is the way we are headed but it will
take some time for the masses to accept a new technology.</FONT></DIV>

<DIV>Ok this has probably been discused but I never payed attention till now.
My question is can you use Li-poly's instead of Li ion's or nicads? Would the
regulators have to be different? What about regulators over heating? How long
would a 2 cell 1200 Li poly pack last before needing a charge? Is this the way
were headed? Thanks, Mike </DIV>
