I agree, batteries cost too much. However, if you compare the cost of a 3S1P 2100mAh 16C pack ($45-$50) to the cost of the fuel it will replace over 100 flights, the LiPo costs less but something more than 50%.
I try to parallel enough cells to get the C requirement at full throttle below 6C so that I know I'll get a solid 10 min.
That can be a good point, but what are you going to fly with that pack and for how long?
