Protection Mechanisms
									Soft Start
			Protection
			 			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.
