I done this on my 8UAFS a couple years ago. Was setting up a plane & when done I put it on the charger but forgot to turn the radio off. Sat like this overnight at least 15 hrs. Got out to the field & discovered the battery was completely drained. I've got a Hobbico quick charger mounted on my field box so this is what I used. Quick charged it in about 45 minutes & was up & flying. Still have this radio today & fly half my planes with this radio, the other half I fly with a 9CAP.
