RE: *Airtronics RD8000 2.4 GHz*
Well I had my tx batteries charged overnight Sunday to Monday (9/8/08), didn't get to fly because it was too windy but ran the engine with the radio on for about 15-20 minutes for testing. Since then, I have turned the radio on and off a few times and as of today (9/11/08) the meter still shows 10.2 volts.
