Kid, I use the volt watches on all my planes. The issue with charging is that it is easy to overcharge. I've blown a couple packs doing that. The Ni-Mh comes with a warning to not leave it on the trickle charge as it will over charge. I look at my fleet of chargers and the only one that claims to peak charge without over charge is my field charger. My plane is usually at about 3/4 or more when I get home, so if I'm going out to the field again in the next couple days, I just wait until I get out there and top it off with the field charger. I'm currently running 1000mah Ni-Cad packs and with my field charger, it is only a maner of 10 minutes or so to get it back on top. The transmitter though is a different deal. The battery is like the bunny add, it just keeps on going. With the Ni-cad that was in it, I couldn't get it to hold over 10.4V going from the charger to the field. This was with a new battery. The Orginal 600mah got side tracked after a few months. With the Ni-mh I'm not using, I can't see a need to cycle it because it still has almost the full charge the Ni-cad had after a number of fly days. I don't dare top it as that may over charge it. I'll waith until I get down around 9.5V or so and then cycle it back up. I guess I could get another field charger and do both the receiver and transmitter at the same time, but what I'm doing now works well.
