For the Warp Drive Prop, I had to physically take it off the shaft to get at the bolts that let me change the pitch. If you have a spinner, this increases the time required. >Can you generally get enough increase in cruise speed to make it even worth >it on a four hour cross country or will the added time to get to high cruise >altitude make the whole thing a wash? The pitch is how far the prop blade moves forward in one revolution absent drag.Changing pitch from 49 to 54 is 10 percent increase in forward movement (reduced by drag) so, it depends on how clean your plane is vs how much climb you need.
