I guess I'm being ultra-conservative with my NimH's then... I don't let them get as far down on voltage as the NiCds. (but having 4 times the capacity... I'm still getting more than 3X as many flights per charge.

)
I'd always prefer to quit thinking maybe the battery is getting low... than to fly thinking maybe I can get away with it and find out that I couldn't get away with it.[:-]
