I am looking to upgrade my Amp MT but I have a few questions first. I don't know if I want to get the fast eddy bearing set or not, what difference do they make? Also, if I was to get a new servo such as the Power HD 1501MG would I need to get the servo saver as well? And most importantly what transmitter and receiver should I pair with it? I also know I want to get a Lipo battery and charger and the metal gear set.
