<DIV><FONT face=Arial size=3>FlightPower has a new series of packs they're
calling "Eon" and claim greatly enhanced cycle life. I'm not aware of anybody
who's used them yet or if they're even available (the announcement came out a
couple months ago). I flew FlightPower Evo's last year with good results.
When new, they made too much power and I actually dual-rated them down to a more
manageable level. After about 50 cycles, they seemed to settle in to a more
manageable level and stayed constant for the rest of the season. I plan to buy a
couple of pairs of FlightPower Eons this spring to try out and also have
available if the Evo's start losing power. My limited experience (3 seasons) in
electric is that most packs will run strong the first year and then drop to
unacceptable levels the second, at least, that was the case with the batteries I
flew my first two years. In fairness, and I won't mention the manufacturer, I
didn't store them properly out of ignorance, so that might be a reason, or the
reason the power dropped off the second year.</FONT></DIV>

batteries</DIV>
<DIV><BR></DIV>OK, new subject: All my sets of batteries were close to the end
of their useful lives this last season. All are showing fairly high
resistance values and most were noticeably down on power. Shot.
Kaput. <BR>Soo.. I've got to go invest in four sets. Tru's lighter
sets enable me to make weight--but I'm not crazy about the durability with
some of Orland's experience--although they have replaced bad(slightly
squishy--puffed would be too strong a term) packs under warranty. I
don't know how their larger and higher rated packs hold up and they 'only' put
me over a couple oz. Price is pretty good.<BR>The older Tanics I had
actually held up the best over time--but the newer ones have not--and fairly
expensive--but I drive by 'em twice a day and wave. I had a set of Kokam
4800s and they didn't hold up well either and I think they have abandoned the
larger battery market-- were/are expensive. I'm hearing
Flightpower mentioned often and wonder if they have a battery guru that
gives pattern guys a break. I never really got serious about TP as at
one time they had--as far as I was concerned--too many cells in their
packs--but perhaps it's time to re-visit.<BR>We also had some of the original
FMA 5000s and they weren't all that great either--but may have improved with a
new cell vendor.<BR> <BR>So I'm in a bit of a quandary. Any
thoughts? This should be interesting.<BR>RS<BR><BR>
