RE: A Beginers Guide to RC.
What battery are you asking about?
Motor battery? I just run it down till the ESC cuts it off
Radio battery? I leave it charged. Will run down on its own just sitting. If you do turn the radio on, put at least a couple of the antenna sections up, but not all of them. Also, do this in a basement if you can. Remember you signal has the opportunity to shoot someone else down. How far are you from the flying field?
And, I would only do this every other month or so. Today's NICDs don't have the severe memory issues the older ones had. If they are NIMH, no cycling is needed on a regular basis. Once a season or twice a year would be plenty and maybe that is more than needed.
