Ouch, that's pretty serious money. Even at 60 mpg you use ~1,666 gallons in 100K miles,  so then at 100K you spend $3,700 for batteries, that would have bought 1,850 gallons of gas!  Which means the car only effectively gets around 28MPG.  Sounds like somebody is pulling a fast one here on the american public.

  FYI on the Prius batts.......Toyota warranties them for 8 years or 100K miles.  After that?......Current replacement price for the entire pack is aprox $3700 including labor!  Wow...A  bargain.......  Price may go down as time goes by and production increases (smile)....John G.

    Mike,
    I did talk with Jim and have a canopy coming. Thanks for the info on that. And it does look like my temptation will have my tried and true OS1.40 in it. Electrics will have to come a long way before it's competitive for guys like me. I only went through a case and a half of fuel this year (9 gallons X $11 = $99). Those batteries would have to last me 7 years for the financials to work out. I wonder how long the batteries will last in the Toyota Prius? That'll be a shock for people when they have to start replacing 150 lbs worth of Nimh's. 
    Jeff

       Jeff E Pattern is still a tough proposition. It'll be cool when the technology and the costs make it mainstream. Until then I'm buying a new YS DZ 160 and keeping my fingers crossed that it doesn't blow up! Mike

        Ouch. I was hoping it to be closer than that. I keep reading about these 
        large scale electric planes being flown with 28 Nicads or nimh, they must 
        not have the performance we need?
