Description
High torque/ultra high speed narrow band programmable digital standard 83g brushless servo with titanium/hardened steel gear and triple BB-ed output shaft. Works great as a tail servo for 500-800 RC helicopters featuring advanced gyro/flybarless control systems. All-aluminium case for perfect cooling under high load.
Narrow band servo – 760 µs neutral, refreshing frequency up to 666 Hz – only to be used with compatible gyro/flybarless control systems as the tail (yaw) servo. It may not be connected to the regular receiver channel output (1520 µs neutral). Always be sure you have set the correct (narrow band) servo type on your gyro/control unit.
Programmable Functions
- Servo Angle: Maximal servo rotation angle range setting.
- Servo Neutral: Servo neutral (centre) position setting.
- Damping Factor: Servo damping setting – adjust the characteristics of the servo when stopping.
- PWM Power: Adjusts the servo output power. The higher the power, the higher the speed and torque of the servo – indeed also the current consumption will be higher.
- Sensitivity: Servo sensitivity (Dead Band) setting. The higher sensitivity the narrower the dead band – servo moves only if the change of the signal pulse width is bigger than the dead band width. Too high setting may cause servo jitter in some applications.
- Soft Start: Turns on/off the soft start feature. If ON, the servo goes slowly to the initial position corresponding to the servo signal once the power is switched on.
- Reverse: Reverses the servo movement direction.
- Lost PPM Protection (Fail-Safe): In the case the control signal from the receiver is lost completely or cannot be decoded correctly (due to interference) the servo can use choose one of three fail-safe modes:
- (a) Release: No fail-safe protection.
- (b) Keep Position: Keeps the position corresponding to the last correct control signal.
- (c) Go Neutral Position: The servo returns to the neutral (1500 µs pulse width) position.
- Over Load protection: Enables or disables overload protection of the servo in three levels – once the overload conditions last for the pre-set time (in seconds), the output power of the servo is reduced to the corresponding pre-set level (% of the max. power).
- Default: Restores the factory default setting of the connected servo.
