2nd Start - Tied to a tree in the front yard. Started the engine and ran at various speeds. The EFIS was not displaying RPM so I did not run long. I did have a digital optical tach on the glare shield to give me some idea of the RPMs.
She stared easily and ran fairly smothly.
Later after research through MGL (EFIS manufacturing) I was able to set the RPM setup screen so that the RPMs displayed.
