Bottom line is.. These servos have been out for ages. As far as technology goes. We're all just getting screwed by marketing. The little digital board just keeps getting updated to let more current go through the servo. Thus making the torque higher. So it's not like there's any real technological break throughs going on here. It's just the demand for higher torque due to newer flying types. AKA 3D/high alpha and larger aircraft. Anyway.. So i guess if I used 5955's for 5 servos.. Flew a flight for 10 min.. Constantly doing 3d.. Based on 3400mah(mili amps per HOUR).. 3400 x 5 divided by 16(10 minutes meaning 1/6 of an hour) = 1062. I think I'm heading in the right direction? Maybe? Maybe not? So a 4200mah pack for instance would last for 3, maybe four 10 minute flights????
