Would .17 sec. speed on a servo be good for 3D? Granted people say the faster the better, but I would like to know if I can get away with servos that have this speed. Could always go with less expo to, right? The servo's would be Hitec 625MG's or 5625MG's on 4.8 volts. I'm leaning towards the digitals to since they're only a few bucks more.
