RE: Help calculating remaining flight time with LiPo's
the voltage you listed is nominal per cell. fully charged, they'll go to about 4.2v/cell. flight time would have to be calculated based on average current draw: if you fly wide open the whole time, then motocalc gave you that number. if you're flying @ about 5.25A, you'll get ~15 min. there's no way to calculate exact flight time. throttle variations, props, wind, you name it will effect how long you can fly. i can say that the discharge curve is relatively linear. i get good power throughout my flights, until LVC kicks in. when i go to charge the packs i find i'm putting nearly capacity back into them.
