Futaba BLS251 S9254 Digital Heli Rudder Servo is designed specifically for helicopter rudder operation. This hyper fast digital servo is ideal for tail rotor control on helicopters as well as many other applications requiring the ultimate in speed of response, yet still requiring good torque.
This servo features a Brushless motor that lasts longer and operates at a lower temperature than a brushed motor with 30% faster response times, smoother operation and a dual bearing gear train.
Compatible with Super Narrow Pulse (760µs) drive.

wow! this servo is freakn fast. running this in my hk550. need to run a step down voltage reg for a max of 5.1v Using the futaba gy520 gyro which is a perfect match. Just remember to set the gyro for a 560Hz/760uSYou can't go wrong with a genuine Futaba product. Excellent tail servo that complements the Futaba 601, 611, 701 and 750 gyros on 4.8 volts for the best performance. Far better choice for the money than the Futaba 9251 or 9256.No doubt about it, this is one of the best rudderservo's on the market.
I use them in all my heli's, never had any problem. Trex 700E, 600Pro, 550, Logo 600SE.The best servo for heli ruder in 4.8vgr8 servo and gr8 price
