batteries have a mortality rate that puts the per flight cost very near the same as glow.
If batteries lasted longer then they would be cheaper but they don't.
Yup, as I've found out the hard way.
It's far easier for me to purchase eight gallons of glow fuel and tell the "significant other" that it will last the rest of the season...
... than it is for me to explain the credit card charge for yet two more 18volt 4800mAh LiPo packs... Ouch!
