No, go for it.Whatever you buy will be onbsolete in two years, so doen't
worry :-)



Mind you, I was such a skinflint I never quite bought any NiMh so am
going direct from Nicad to Lipoly.


Isn't it fabulous? Suddenly duration and weight are - well not no
problem at all-, but certainly MUCH easier to get to.
Astro 109 is the best charger around.

If you buy a battery/motor/computer thats fast as butt, not even the 'ultimate' available,
but one that'll perform great and is affordable, who cares if its obsolete next week. In
two two years you'll still get 45minute flights and plenty of vertical. Unless your trying
to show off to the guys in the club, the most current *anything* is almost always
overkill, and for that premium price you only gain a few months before everyone else in
the club has one.
Im prolly not going to go lipo for a while - all my Black-ops slush fund cash will be
funneled into this .40 trainer someone gave me. For now, nimhs will have to suffice.

Also, in reviews, the ReZap battery charger opinions are negative.
Said it doesn't do the job.

Thanks for the encouragement, but things do become obsolete way too
fast.

You are very fortunate to have waited. I spent a considerable amount
on NiMH already and now I'd like to turn to Li Po batteries for their
lightness and capability for longer flights.

> Isn't it fabulous? Suddenly duration and weight are - well not no

Yes, it is fabulous. I had just returned from an indoor fun fly and
those little planes flew all evening on one charge with Li Po
batteries. My plane is a Slow Stick, a larger plane and it didn't use
much of the battery. Probably enough charge left for a couple more
evenings.

> Astro 109 is the best charger around.

Well, I have a Triton charger now. What I'm concerned about is, if new
technologies develop new and better batteries, will my charger still
be compatible?

Already they're talking about the "new and better". That's the reason
for my original question. Since outdoor flying around here won't be
for a few months yet, should I wait?

Obsolete? No. NiCds and NiMH cells work just as well (often better)
than they used to. It's just that Li-poly cells are often better now
for many applications.

Just because there's something better out now, that doesn't mean that
what was out yesterday is obsolete.

Still, in your case, it sounds like Li-poly is a good thing. You'll
have to tell us how it works out.

Personally, I haven't made the Li-poly plunge yet. But soon. I've
already got an appropriate charger (GP Triton) so it's just a matter
of buying the batteries and maybe an ESC or two that will cut off an
at appropriate voltage.

Doug, I know you've been around for quite some time and you're right
about the NiCds and NiMH not being obsolete yet, but soon the Li Pos
will replace them. Just guessing, as I'm beginning to learn about this
new fangled stuff.

That's just it, Li Pos are lighter and has better flight duration,
because as you know, lighter airplanes don't need as much power to fly
and fly better to boot.

I will let you know, but warm weather is still months away here.
However, there are many fliers who have been using and are very happy
with this type of battery.

Once you have the basic electric plane, the investment in new Li Poly
batteries and access. are a lot less costly. (I also have the GP
Triton). In my case, I need only to buy the batteries. Got everything
else.

I've said earlier, I flew indoors a Slow Stick all evening powered by
a Li Po battery and yet have enough power for a couple more evenings.

Sure sounds as if I'm convincing myself to buy right away.

I just wish the triton was ac/dc. Hard to imagine they went through all the trouble of
making that capable of charging anything, but they couldnt stick a powercord out the
back...

it'd take a lot more than just a powercord....a power supply that'd be
two or three times larger than the charger itself. It'd no longer be
a nice compact little unit that you can take to the field in your
flight box.

Exactly so -- a 13 amp 12 volt power transformer would not be small.
It would also increase the price.

You can convert a PC power supply into a nice power supply for things
like this pretty easily. Here's instructions --

http://www.marcee.org/Articles/PCPowerSupply.htm

much cheaper than anything you'll buy at Radio Shack.

Hint: try to find an AT power supply rather than ATX -- it's easier to
do with an AT power supply.

I am using a power supply that I bought at : http://remboy.com 12V @ 13
amps or $19.95 including shipping. It is about 1.5 X 4 X 8.

It is mounted in a small field box along with a 7.5 Ah battery. Works great
and I can use it in the field or at home.

You have some nice looking designs, Mr. Eastman. Wish I could think of
a name for the twin powered plane. How about "High Tailer"? I'm not
trying to enter your contest though : )

I did say that I have a Triton charger, but it is fairly small,
measuring about 1 1/2" x 4" x 6" that could use the battery directly
off my car. This I could take to the field.

The AC power supply is about time and a half larger than the Triton in
volume. A little thicker and wider, and about 2" longer. I leave that
home.

I wonder if there are more compact chargers out there?

Thanks,
Wan

yes, but that wouldn't be the one that a manufacturer would add to
their product. to practical, not big enough. <VBG>

ever see the AC one that powers the accucycle plus?
