I have hitec digitals all the way around in my showtime, powered by a NOBS 5 cell 4/5A 1900 mah pack. Got plenty of juice for the servos. ON this type of plane the crisp precision from digital servos will really shine. On top of it more holding power. Ill never go back to analog again. And now you can get the hitec 5645 servo for almost 50 bucks with almost 160 oz of torque. You just cant beat that.
