I closed your quote there Dick.

I stand by my post.... well, actually I sit in front of the monitor by my post...

Some playing with props will/may find one that provides the same thrust but with less power going into the prop. In particular if the prop has a significant amount of front/upper surface stall or pre stall separation drag. That drag has to be overcome by the engine to provide the thrust needed to hold the model up. If a different prop can provide the same amount of thrust but without the need to input as much torque because the air flowing over the prop blades does so in a cleaner manner then the engine won't be generating the same amount of torque.

You may have heard this with some of your electric models. Some props produce a sort of frying bacon zzzzzzzz sound while others, usually with a higher pitch, produce a deeper and "fluffy" sound. I can't describe it any better than that but I know it when I hear it. If you're using an ampmeter at the time you'll see a big jump in current (torque is directly related to current in electrics) with this new prop and a huge drop in thrust per amp. SInce this seems to occur quite regularly at around the 5 to 7 inch pitch range I sort of came to the idea that it's related to the blades operating in the stalled region or with some separation taking place.

I agree that for the model to hover it needs to generate the same amount of thrust from the prop disc. But nothing says that the prop disc can't do this with very littl eor a lot of drag. But if the prop has a lot of drag while doing it then the torque needed to overcome that drag and produce the needed 1:1 thrust will require more power than one that does this with very little drag.
