Helical Gears, Brushless Motor, Digital Control, High Voltage.
There is a new king of all servos in town. Introducing the formidable Bluebird BLS-H71B! This BEAST makes nearly 1000 oz-in at 7.4 volts making it a class leader in both performance and value. We learned from the success had with the BLS-H51B and BLS-M52B and put those models on steroids to make this new servo posible.
The BLS-H71B is everything you would expect from Blue Bird Servo. Monster Torque, Fast and buttery smooth. This high-voltage beast will not disappoint.
