Default Positioning the prop

What is the best position to place the prop in relation to the start of the engine's compression stroke so that in the event of a dead stick landing the prop stops as close as possible to a 9:15 position, or is it different for each engine/prop combo and so trial and error is the best way to achieve this.

Default RE: Positioning the prop

For 40cc and larger place the prop at 1 o'clock start of compression for safer stand up starting. Don't wory about dinging a prop in a deadstick. Way better than kneeling to start an engine and have it get loose.

No one plans on having a deadstick, but in the event that it does happen I'm not really worried about dinging a prop on my 20-26cc motors, what I am concerned about is the possibility of my wacking it hard enough to get either the prop hub or the crank out of alignment.
