Reminder -READ THIS!
ALWAYS be respectful of your engine and prop whether it is running or not.
I had a close one at the field today. I was having trouble starting my engine with my starter, so I decided to flip it around to see if it was flooded.
I forgot to remove the nicad.
Fortunately, my engine still did not want to start, and the firing only flipped it around once, which did not break my skin, and I can still count to ten without taking my shoes off.
It's embarrasing, as I have always been _very_ cautious about the running engine, but I want to post this in hope of preventing someone else's tragedy.
