Today, I riveted on the Engine Control Sub Panel. I'll order the controls after I install the engine and can measure the correct lengths. In addition, I finished securing the Transmonspe with a WDG-21 Adel Clamp. I then installed the ADSB UAT and GPS antennas. The UAT antenna is one bulkhead back from the avionics tray for the unit, and the GPS is one bulkhead back and above the unit.
