RE: E-FLIGHT BLADE CP
skymortar, average is 2.5 HRS. for NI-MH with stock charger. You need to check battery often and unplug when battery feels hot (caused from resistance in batt.). If you use adjustable charger you can charge at 750 MA for 45 minutes on a 650 MA stock battery.
always remember heat kills battery's, let them cool before charge or recharging.
