After I typed the previous message, I watched a video clip of a "3D" flying, however, the torque roll was not performed in a narrow space, or in other words, the plane was rolling all over the SKY! Is this the optimum way of torque rolling?

Can you torque roll while the plane is only inches off the ground ! If my memory is ok, I remember watching a clip of a pilot torque rolling an Ultima just few inches off the ground!
