I hand start sometimes. Lots of times my engines just will not start without an electric starter. I for some reason have a very easy time starting wood props than nylon. Not sure why that is. Usually i just use an electric starter though.

BTW, i have used my bare hands many times to flip start but usually use a glove. IMO, i just can't get the feel with a chicken stick.
I have hit my bare hands on a few engines and it never cut my hand but i am in no way suggesting a begginer to use his bare hands
