RE: Hitec 5645 servos, Are they good servos?
I have some in a 28% WH extra. They do not center as well as the more expensive Hi-tec servos. If I were flying IMAC, I would probably go with something better. For $45 ea. what do you expect?
BTW, there is a forum just for servos and other radio gear, you might get a better responce over there.
