Rappy,
If the engine is broken in and properly tuned it can be very easy to start.
If it is out of whack in any way your arm may give out long before it starts.
Get the starter, make sure all is running well, use the chicken stick as a backup.

I've seen guys land and kill the engine or dead stick, walk out on the field and make a quick adjustment, start it right there with a chicken stick in their pocket and take off again. A good thing to know how to do but don't depend on it.

Good Luck,
