Welcome to the next level. If you want an all out bone crushing power house of a servo then look no further. Pick your application but if you want to outfit your 40% 50% 60% or larger giant scale rc aircraft then this is the sleep well at night servo. If you are into heavier RC boats and rc cars, trucks and buggies then this also a rock solid choice while saving weight over some of the weeker 1/4 scale servos out there.




Application / Suitable

Awesome for 1/5th Buggy / Monster / Crawler, Off-Road Car & 3D Aerobatic​ Airplane, Turbojet.

Protection Mechanism

Soft Start ProtectionSoft start back to neutral position.
Over Voltage ProtectionOver 9.0V drive the protection mode, and 8.4V return to normal mode.
Low Voltage ProtectionLower than 4.0V drive the protection mode, and 4.5V return to normal mode.
Locked Rotor ProtectionStall in 5 sec, output torque goes down.
Temperature ProtectionOverheat 85 degrees C (185 degrees F), drive the protection mode and down 75 degrees C (167 degrees F) return to normal mode.
Lose Control ProtectionWhen losing the transmitter signal, that servo will immediately be back to the neutral position and locked.
