most good ones are 0.1 seconds and 15kg... there are high voltage servos that can be run with 7.4 volt lipo 2 cells but would not be nessecery for your truggy...the spline count were you fit the servo horn varies with some brands so to run your std horns buy something with the same number spline, most servo come wth the correct one.
