vs. Glow</DIV>
<DIV><BR></DIV>
<DIV>Hi Dave,</DIV>
<DIV> </DIV>
<DIV>Yes, it is evident that electric systems maintenance cost is less
than internal combustion engines. Let's put a number to
maintenance. I know for 2C. I usually fly 300 flights per
year. I will say that I spend the following in a year. Of course,
this is a rough approximation (my starter is 15 years old and still running
well):</DIV>
<DIV> </DIV>
<DIV>Glow drivers: replace one battery per year + glow clips = ~$40/yr</DIV>
<DIV>Engine parts (Pump+rings or other parts) = ~$100/yr</DIV>
<DIV>Additional labor (could be a bigger number for some) for me in the hobby
around = $160/yr </DIV>
<DIV> </DIV>
<DIV>Total is: about $ $300/yr. This add around $1 per
flight. The electric would have some maintenance less say 20% of the
glow maintenance cost. Therefore, the new number including maintenance
cost is for glow $2.64/flight. For electric would be around
$7.60/flight. Including operational and maintenance costs the
electric is about 2.87 more expensive than glow assuming that the life of the
battery is 100 cycles. Clearly the life of the battery or the initial
cost is driven the electric cost. I would say that when the batteries
gives around 150-200 cycles it would be the right time in my case to
switch. Base on the little information floating around the life of the
batteries could be lower than 100 cycles. Of course if the
battery manufacturers are willing to give warranty that is close to the
one we get for car batteries this economic analysis will
change. This is pure eco! nomic analysis, it is clear to me
that for high level pilots electric is definitive strong
advantage and could be one or two spot difference in
final contest results. For sponsored pilots there is no way to
put dollar value since they are getting free equipment.</DIV>

<DIV>And the cost of support equipment - glow drivers, electric
starters. Support equipment for the electrics is less prone to
wear/tear and need to be repaired/replaced.</DIV>
<DIV> </DIV>
<DIV>And then the cost of maintaining the powerplants themselves - Properly
setup and maintained electrics need little or no maintenance. And then
there is the time savings (different people will put a different value on
their time) of not having to do the additional maintenance for the
glow.</DIV>

<DIV>That may be true if you're considering fuel costs only. I would
think it's fair to factor in the savings realized by not having to
frequently repair/replace your airframe and radio
equipment from vibration induced wear and damage as
well.</DIV>

[NSRCA-discussion] Fuel Weight</DIV></DIV>
<DIV> </DIV>
<DIV>I spend around $15 per gallon (20% nitro, 2C). That means
that the cost per oz is about $0.12/oz. I spend about 14 oz to
fly the Master schedule with normal winds. In Muncie we should
use around 16 oz (2C engines). This means that the glow fuel
cost is about $1.64/flight. For electric, the question is
how many cycles is the average life of the batteries? Let's
make it easier and assume that the average life is 100 cycles.
This means that the cost per fly would be $7.40/flight.
Clearly, electric is 4.5 times more expensive assuming that 100
cycles is correct compared with 2C engines. My personal
conclusion is: I will wait until the battery manufactures give
us at least equal guaranty that we get when we buy batteries
for cars.</DIV>
