I have 4 planes that I normally like to fly. I usually go flying spontaneously and I would like to keep the RX batteries toped off. Do you think it would be aok idea to leave the RX batteries on the charger all the time (after they are fully charged) and have the chargers plugged into an outlet that is on a timer for 30 minutes or so a day? I am wondering if that is a bad idea for battery life or capacity issues.</p>
