Now when its time to fly would it be ok to disconnect motor from ESC, plug in battery, then plug motor back into ESC when Im ready to throw it and have it do its thing? My connectors for the motor and ESC will be external so thats why I was asking. That way I can open the plane install battery and put it back together without the prop spinning

Second questions sense it still deals with the topic of Lipo packs, is it a good idea to get one of those "bags" that your supposed to put the pack in while you charge or is something like that more of a gimick?
