I always leave the glow starter on until I am behind the plane. I move up to behind the wing then reach over the wing for the starter. Every once in a while I find myself reaching for the glow starter while still in front, but stop and go back around. I have had 19 stitches in my right hand from a prop. I don't need that to happen twice to convince me to get behind it. It's ironic, when working on a table saw I never reach across a spinning blade, so why should it be any different with a spinning prop?
