OK guys. I purchased a BVM T-33 kit from another modeler. He had ALL the JR servos required to fly the jet as recommended by BVM at the time he purchased it....all analog. Should I use them or buy new digital ones. I will be using a Spektrum 12ch power safe RX along with my trusty JR 12X. It will be a big investment to turn around replace them all with digital JRs. Comments?
