Linear feedback unit


 

The linear feed back unit is mounted direct on the integrated Linear drive. It is very easy to fit in the prepared fitting holes. With the linear feed back unit the rudder angels at big rudder angels are distorted but that will not effect the steering of the autopilot.

This unit is not recommended to use together with the analogue rudder angle instrument.

How to get correct value of the resistor to the linear RAT, depending on the angle of the rudder and the length of the tiller arm.

In the table below you will find (from left to right): Which length of the tiller arm you can use, which maximum rudder angle you will get, which exact value of the resistor it will be with the specific rudder angle, which value of the resistor that is a standard resistor, which maximum rudder angle you will get if using a standard resistor value. The last column, "Part No. Elfa", is a part number to a Swedish company selling the resistors.
