PROTECTION MECHANISM
| 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. |
