Here is some progress on my MTH AFT GS4 Legacy Conversion. I got the motor encoder installed onto the motor. I had to slightly enlarge the mounting holes on the PCB for the sensor to align properly with the flywheel ring. I used my dremel to lengthen the slat spot on the motor output shaft to allow the set screw on the flywheel to seat better. I also ground down the tops of the motor mount screws to allow the encoder ring to not the hit the screws as it spun. Got working on the tender as well. Drilled holes and mounted the RS Lite and the LTC1 board. The speaker and switches were already installed previously. Looking good and hoping to get more done soon.
I put electrical tape behind the PCB to prevent it from shorting out on the motor
