Today I replaced the Trutrak autopilot trim servo with the Skyview autopilot trim servo. The mechanical replacement was simple reqiuiring only the redoing of the securing wires. I needed to mount and wire a DB9 connector and lace the cable coming down from the ADAHRS platform. I separated the pitot line from the rest because there was not enogh room in the bulkhead feedthrough hole. Fortunately, there was enough space in the lighting conduit to get the pitot tube through.
