on the lower engine cowling, the part that swings down, on the left side of the aircraft there is a notice printed. It's on almost if not all Me 109's. Does anyone know what it says?
Do you mean the one? If you do.... this is a warning." Vorsicht beim Öffnen. Kühler ist im Haubenteil eingebaut " which means " Careful when opening. The cooler is built into the cover ". The notice can be seen on engine cowlings of Bf109 F and later variants mostly.
