Perhaps post some pics of what you have done physically with the mounts etc so others can suggest some ideas or modifications ......

The only other issue I had with my 5010's was that I used a loose fitting metal washer on the Old Pot Shaft 1st time around as a spacer and I think it was rotating and effecting the magnetic field,
that I fixed by replacing them with UHMW Plastic washers.

Is that the Rudder in the pic or one of the toe brakes ? certainly looks a bit weird to me ...

after you calibrated the TLE5010 in MMjoy did you set the Calibration to a saved typed --- either with or without centre ...with for rudder without for toebrakes...
