Things are actually coming together rather nice. The MIP is wired up and I took the sim for a VATSIM-flight. Got my self started in Hamburg, Germany. While holding there I tested a lot of things – among other – the rudder, elevators, ailerons. working. About half an hour later – take off. And all of a sudden the ailerons are not working. The aircraft banks to the right and continues to do so until it is up-side-down and I have to disconnect. Turn out my home make yoke is dead. So I had to pull it out from the cockpit this weekend to find out what was wrong.

Testing with a multimeter there was no signal from the potentiometer for the aileron. The yoke is not easy to take apart. The easiest route for me was from the bottom up. Simply releasing the column from the base and take it apart from there. The potentiometer for the aileron is located inside the column.

Fault: The potentiometer had come loose from its plug inside the column. These connectors always have seemed rock solid and all wiring has been tied down to prevent any movement. But apparently not enough. Appears there was a tension on the wire where it goes from the column to the base. Combined with gravity – notch by notch – made it come loose. So from now on connectors are hold additionally in place with a zip tie

While having the yoke out I also switched the potentiometer for the elevator. Originally I mounted a turn-potentiometer with an arm that would read the movement of the elevator. However the travel was too small only about 1/3 of the full resolution of the potentiometer.
Therefor I have changed to a sliding potentiometer. It is connected to the elevator column by an arm. The length of travel can then be adjusted my lowering / raising the mount point on the column. So I hope to achieve full length of travel this way.
