Hi Guys,
I have renewed my ears onto the list. Having been on the list since the
beginning I have been off for the last eight months or so and dearly missed
the chatter. I sold my hobby shop, my house and started a new business,
importing lipoly batteries, and other supplies for rc hobby people on line.
I sure am happy to be back.

John,
The Idaho back country group is planning on being at Caldwell sometime early
afternoon tomorrow and then on to Smiley Creek for the night. Eventually we
want to get to Cavanaugh Bay and then maybe in to Canada for a short visit.

Great that you are back John.
You have knowledge of things developed first in models
that will eventually show up on 1:1 scale. And they
are lighter in weight too.
Speaking of batteries....

Kurt,
Thanks for the welcome, like I said I have felt darn lonely the last few
months. Speaking of batteries, we have been toying with the idea of making
my fox lithium powered, for the fun of it.

John,
What are the most light weight batteries that are used
on electric planes these days - Li?
Make sure it isn't a Dell.... HA ha
I suspect we could cut several battery pounds off,
give enough $.

Kurt,
The current lipoly batteries are by far the best power per pound. Currently
they are capable of as much as 50C discharge rates and 3 to 4 c charge
rates. For our UAV projects it has moved us away from nitro and gas power to
high horsepower motors. We now can run a 12lb chopper for 45 minutes with a
15lb weight (Computers, cameras, guns ect) on board. Lipo batteries for auto
in Europe now run 144volt systems using lipo's that are the size of a note
book sheet of paper and an 1/8th inch thick and hold 20 amps each. Several
people have flown manned glass airplanes for over 150 miles on battery
alone.
I believe the Dell bat. Problem is in the pack wiring and not the cells.
Lipo battery fires are nasty, but can be controlled with normal equipment.
The future (month or two) is li-nickel; they are capable of 100 C discharge
rates... cool stuff.

John,
I know of one group working on a 500 mile range 2
seater, but they will convert to fuel cells in the
final form. Fuel up, turn on, go....quietly.
Way lower maintenance.
If the new bats can be quickly swapped out, have the
range, and can be recharged and operated at low enough
cost, they can compete with fuel cells.
It is not the big guys, but the little guys who
innovate the most.
