RC OMG H4-ST-BF20S "High Torque" Brushless Aluminum Case Metal Gear Servo (High Voltage)
Very high quality servo. Geartrain is extremely smooth and silent. No digital noise or chatter like I'm used to seeing with my other digital servos. Running in an SCT with no servo saver, has taken many hard hits some even popping off the steering linkages and still works and sounds like new.

RC OMG H4-ST-BF20S "High Torque" Brushless Aluminum Case Metal Gear Servo (High Voltage)
This servo is super fast with tons of torque and it's SILENT. None of the chatter/buzzing while holding center like every other servo I've used. When it was powered up and holding center and I was torquing down the servo horn, it never made a peep. I'm running mine at 7.4V which gives a nice increase to speed and torque. This thing has plenty of both. Installed on an RC8B3e with a Tekin RX8 ESC with no additional caps or external BEC.
