ORIGINAL: Big feet
I have heard it said that a good lipo pack is just like XX number of litres of fuel, true, but then again we don't need to but XX litres of fuel all in one go.
I'd like to know that quote. For my Trex 450se using a 2200 3S1P the equivelent for that size helo whould be 1oz of fuel per flight (small motor, short flight times), I could see the battery lasting 100 flights on average before it's poofed for some reason... 128oz = 1 gallon. So $70 battery = $16 gallon of fuel... it would take more than 500 flights to break even...
I await the flaming...
