Unless you have more batteries to change out while the other is charging. Nitro will need charging too depending on the flight pack capacity. I usually carry 3 packs for each plane. That way I avoid field charging (for electric planes). The flight packs in my nitro's are big enough to support 5-6 flights each with no worries (probably 10 flights but I don't push it). Go to the nitroplanes forum above this one and read before buying. There is a ton of info there.
