Default Pre stretching cable/ Prop differences

Not clear enough? sorry I will try and be a bit more clear.


A pull-pull cable system over time will stretch in the plane, I was told to hang them up and place a 10 pound weight on one end for a given time before installing in the plane to pre-stretch the cable. The time given I am not sure of.

On the prop issue, I am familiar with boat props but not plane props.

ie: A 19 pitch boat prop offers low end torque but takes away from top end speed. A 21 pitch boat prop offers low torque out of the hole but give more top end speed.

I was just curious to know how a plane prop works dia/pitch etc....

Thanks
