does me the whole day, i was using it on sunday last week, wednesday and friday and i hadn't recharged it at all, rattled off close to 450 shot's and she still got life in her. so i'd say give it a go. so far i've used it in the last week for about 5 hrs shooting, still registers as full power.
how's the 20D? as good as you expected?!?!
seem's you and i may well be the only people in Oz shooting planes with it!
