Trimmrad

[Baron58]

Hi
first of all sorry for replying in english, i can read German, but writing is a step to far.

I have built a trimwheel and indicator for a twinprop (Baron 58 ).


I used a rotary encoder instead of a potmeter so I have no absolute zero and have relative movements of the trimwheel instead of absolute 9which is the case with a potmeter). The indicator is controlled using a servo. This way it does not matter if the trim is set by the autopilot or by the traimwheel. in both cases the indicator will give the correct position (The servocontroller reads the right setting using the FS2004 offsetvalue for elevation trim).



Trimmechanism including a servo to steer the trim indicator in the housing (the 3 wires of the servo are visible.



Trim wheel indicator (the arc on the picture). On the arc the scale will be glued. Indicator is driven by a servo and a gear. The indicator moves free over the metal axis. On the axis the trim wheel will be assembled (fixed). The metal axis is connected to a rotary encoder.
