Garmin GRF 10 Rudder Feedback Sensor

this is an example of a properly configured rudder feedback unit or RF u the RF u is on the left and the rudder rudder stock and rudder stock adapter bracket are on the right you can see here that the distance from the center of rotation of the rudder reference unit to its ball socket is equal to the distance from the center of rotation of the rudder stock to its ball socket on the rudder stock adapter this results in a 90-degree angle between the rudder arm the linkage rod and the rudder and rudder stock adapter in this configuration you can see that rudder angle movements are matched exactly by angles on the rudder reference unit so a 45-degree deflection of the rudder results in a 45-degree deflection of the rudder reference unit this is an example of an improperly setup rudder reference unit where the distance from the center of rotation of the arm to its ball socket is much less th
