[NSRCA-discussion] Fuel Weight

[DaveL322 at comcast.net]

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.

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.

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
