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.</span></font><o:p></o:p></p>

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>

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. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>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>

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>

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>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
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>

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>
