Protection Mechanisms
									Soft Start
						Soft start to a neutral position.							Over Voltage Protection               			Over 9.0V drive the protection mode and 8.4V return to normal mode.							Low Voltage Protection			Lower than 4.0V, drive the protection mode and 4.5V return to normal mode.							Locked Rotor Protection                  			Stall in 5 sec, output torque goes down.							Temperature Protection			Overheat 85 degrees C (185 degrees F), drive the protection mode and down 75 degrees C (167 degrees F) return to normal mode.							Lose Control Protection			When losing the transmitter signal, that servo will be back to the neutral position immediately and lock.
