AR 8477 HV Soft Start High Torque Servo
The all new AR 8477 competition grade high voltage high torque servo takes it to the next level. Operating from 6.0volts, 7.2volts or 8.4volts, the AR-84 series builds on the success of the super reliable AR7444S servo offering a full metal case, dual bearing for excellent long life usage and gobs more torque and holding power.
Soft Start Function
Gone are the days of jerking controls surfaces when you power up your model. Each time your model powers up the AR8455 servo will elegantly move the control surface to the current signal position and then runs as normal.
