Don't you have radically increased pitch in the prop? That will do it.

Yep, 88" pitch.  Guess I figured even at that blade angle air flow would be fully stalled past the prop and the disk area being larger would cause more drag.  I was obviously wrong. 

Also noticed that having a direct MPG readout makes finding the most efficient descent angle & throttle setting easy to find.  It's a lot different than on the other redrive/prop.
