Steve,
It takes an hour to charge the batteries after a flight, IF you don't go over 9 minutes on the flight. All this assumes reasonable throttle management, of course. However, the batteries have to cool down after the flight before they go on the charger which usually takes 15 minutes or so. One item you left off your list is a tempgun which is vital. There are other niceties like a wattmeter, but it's really critical to keep track of your temperatures.
