I bought this servo for my Short Truck and I have to say I'm really impressed by his quality !
The case is made of high quality aluminum. It provides high torque while its speed is greater than my more expansive Futaba servo.
Gears are made of steel which ensure high resistance for 4x4 cars.
I give a 5 stars without hesitation because it deserves it. You can buy this piece of hardware blindly !
