Calculating Flight Times??
Hey Guys,
I'm sure this has been discussed before somewhere but I haven't found it yet. I am designing a micro indoor 3D plane and deciding how big of a battery to carry. Obviously every gram counts in a 20 gram AUW plane so I want the smallest battery to give me a decent flight time. How would I roughly calculate the flight time of a certain Mah battery to run a 7700Kv micro brushless motor that draws 2.5 amps or so at full throttle? Do I need any other info? Obviously I wouldn't be flying full throttle the whole time, but I'm looking for ball park figures. Thanks for any input!
