[NSRCA-discussion] Fuel Weight

[Rick Kent]

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.

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.

It may be cheaper in the end, but laying out the $$$ to get started is the
hard thing.(4 sets of batteries, chargers, power supplies/generator).

Electricity is a whole lot cheaper than glow fuel - it's just the darn tanks
that are expensive (and heavy)!

24oz is .1875 gallons. Nitro fuel weighs about 7.5# / gal. The fuel weight
would be 22.5oz, but, a pound and a half is close enough for government work

 
I didn't look up the weight of electrons, but one of my battery packs weighs
2.5lb and cost $740 and I still think electric is cheaper ------- and, it
doesen't take creative accounting.                         Nat
