size=2>They'll quit at 10S, or 42VDC. That's the voltage above which electrical
codes (both local and international ) say you need to treat wiring as if
it was "mains" wiring, with insulation and creepage distance requirements. It's
not a big deal, really. You have a house full of wiring, including the
power supply of everything that plugs into a wall, that meets the
requirements, without having to do anything fancy. LiPoly is easier to construct
for high current discharge. With Li-iion, it is easier to get high energy
density, at the expense of current delivery. Some of the early 2S lithium-ion
setups for flight packs were actually dropping down below the regulator voltage
setpoint under peak loads. Don Szczur's Dad diagnosed that one, at least in this
part of the country. It's gotten better since then.</FONT></SPAN></DIV>

style="FONT-SIZE: 12pt">As it turns out, Lithium Ion cells are just as touchy
about overvoltage, and the like. About 75 cell phones a year explode. A buddy
of mine used to be the strategic supply-line guy for Motorola phones. His
contacts in the engineering group there told me that Mot puts overvoltage
protection, internal cell pressure detection, over-current detection,
and undervoltage charge prevention protection in every pack/phone.
That is what they determined to be necessary to make litium ions acceptably
safe. After all that, you hear about problems, ususally with non OEM cells.
Also since all cell phones run with 1S packs, there are no balance
issues.<o:p></o:p></SPAN></FONT></P></DIV>

style="FONT-SIZE: 12pt">Unfurtunetely, I have to estimate the
cost. I did an estimate how much is the cost to run my 2c
motor per flight. At $15/gallon using 14 oz of fuel per fly
the cost is $1.75 per flight. This number is correct since I
usually flight between 200-300 flights per year.

style="FONT-SIZE: 12pt">The question is: what is the life of the
batteries? Base of the feedback I got at the Nats. the life
flying F3A is around 60 flights. Therefore, if I am correct
the cost per fly is $11. Assuming that I do 250 flights per
year the cost of electric is $2,750/yr. The equivalent cost of
glow (2C) is $440/year. With two kids in college my option is
clear. I am assuming that the cost of batteries is $640 but
not sure now. <o:p></o:p></SPAN></FONT></P></DIV>

Clearly the cost of the batteries has to come down or the
cycles have to go up to around 400 cycles to get equivalent cost to
glow. <o:p></o:p></SPAN></FONT></P></DIV>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">The E info on the list
has been scant. Probably some are reluctant to hype / criticize
products because of their involvement with suppliers. Some of us
are just blindly exploring options, gathering data / information,
and forming opinions without experience to back up our
conclusions. Certainly information offered by those with
experience is very welcome and appreciated. Those who are
qualified experts in the various fields that can correct / clarify
information gained through the school of hard knocks are not only
welcome, but I suspect somewhat obligated to protect the rest of
us. As this entire topic expands there will be conflicting
opinions which in themselves provide info - that's what this list
is for and no one should take offense that some prefer other
views.</SPAN></FONT><o:p></o:p></P></DIV>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">After teasing the E
guys at the Nats I recognized that the E powered airplanes flew
better (I'll admit to being obstinate - but not totally dumb).
There were also differences that seemed related more to E
equipment choices than differences in pilot skills. The info
published by Jason, Frack, <st1:place w:st="on"><st1:City
w:st="on">Adam</st1:City>, <st1:country-region
w:st="on">Chad</st1:country-region></st1:place>, and others (in
RCU forums) provided an insight to the various equipment choices
(and passionate defense of same in some cases). Interestingly, a
lot of the discussions revolve around equipment type rather than
the effect on flight
characteristics.</SPAN></FONT><o:p></o:p></P></DIV>

<DIV>
<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">So - I set about
trying to determine if E flies better and why. So far the answer
is yes and I'm not sure. While differences in dynamics can be
identified, it's hard to quantify the effects. For example, the
lighter / slower rotating E prop generates a lower gyroscopic
precession force during looping maneuvers than glow - this also
suggests the lower rotating mass of a geared motor might be
better. The lighter motor (compared to glow engine) up front
can result in a lower pitch moment of inertia if
the tail is light enough to allow the battery mass to be close to
the CG. Airplane smoothness in rough air is markedly better with
E. (I did most of my comparisons with twin Partners - one glow and
one E - at about the same flight weight.) This may be an
effect of the large diameter prop or lack of vibration effect on
the servos. As others have noted, thrust application is very good
with E as the slower prop is efficient and the mo! ! ! tor is
instantly responsive and very linear. E can be flown slower than
or as fast as glow, the airplane is more stable with E when
slow - again probably the large prop effect. Overall, it's
easier to fly well with E but E won't fix sloppy
flying.</SPAN></FONT><o:p></o:p></P></DIV>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">As with most things in
model aviation - there are learning curves. Some suppliers are
better than others, some equipment is better than others, some
choices will be revisited after experience is gained. The hardest
thing to get used to is the metrification of cost - kilo dollars.
Not that E is that much more expensive than glow - just that very
little from glow is useable with E. That means one must acquire
motors, controllers, batteries, chargers, power supplies, meters,
connectors, wire, props, etc. pretty much from
scratch.</SPAN></FONT><o:p></o:p></P></DIV>

this becoming a thread I'll discuss the reasons for some of my

assumptions and some of this stuff will change - I'm still
learning.</SPAN></FONT><o:p></o:p></P></DIV>
