I will leave the discussion with this thought
If it takes 10 lbs of thrust -to hold in stationary hover a 10 lb model -using a simple single propeller - - the prop will need a given amount of power (hp) to do that job . not more or less
the reaction of the applied power at the prop will be equal to the force turning it..
swapping props -as long as the setup will still just hover the model -- will result in same "torque rolling effect".
