 This is the Futaba BLS251 Brushless Digital Heli Tail Servo. Designed specifically for helicopter rudder operation the BLS251 Brushless Digital Heli Rudder Servo is equipped with a Brushless motor. This results in 30% faster response times and smoother operation than servo's with a typical Brushed motor. It also lasts longer and operates at a lower temperature than a Brushed motor servo and uses the same power consumption and centering as a Digital servo equipped with a Brushed motor!
Please note: The Futaba BLS251 Brushless Digital Heli Rudder Servo works only with super narrow pulse width gyro's. This includes the Futaba GY520, GY601, GY611, The Spartan Quark and DS760 gyros or others that use a 760µs drive pulse signal. This servo can produce high-current draw from your batteries. If using NiMH or LiPo batteries, make sure they are capable of delivering sufficient amps!
