Scott,
 
My MT prop is standard hydraulic but it will govern down to about = 1200 rpm.=20 As Gary Casey mentioned, it's more the reduction in engine friction = at low=20 rpm than actual blade angle that makes us glide better with the prop = control=20 pulled out.

Is your MT prop electric?  My understanding is that oil = pressure=20 managed props (non-feathering) would go to a flatter pitch = as the=20 pressure is diminished and the prop slows - perhaps the flatter=20 pitch keeps the prop from actually=20 stopping?.
