RE: Hitec HS-55 servos.GOOD for WHAT ???
Of all the brands of servos I've used (JR, Hitec, Hobbico, Futaba, Royal, Cirrus, Blue Arrow, Airtronics etc.) the only ones I've had out and out failures with are the Cirrus. I've worn out pots and busted gears on other brands but the Cirrus have had wires come off of the motors on several servos. I don't know about their current models, but on the CS21s there is a ceramic disc capacitor that is soldered to the motor and the caps legs are used for the connections to the motor. The motor can twist slightly and because the capacitor legs are solid wire, not stranded, they break off over time.
