Hello Mitch,
For aircraft equipped with constant speed or variable pitch propellers, 
changing the propeller setting to High RPM adds drag - and contributes to a 
higher sink rate.
Conversely, in emergency power off glide situations, changing the propeller 
setting to Low RPM reduces drag - and minimizes sink rate.
