I've been flying on G2 multi-player ever since it came out and i have yet to find anyone that can hover any of the planes in there.
I have over 100 downloaded planes and schemes and none can actually HOVER.
To be more specific, Hovering is keeping the plane in one location facing one direction for extended periods of time (tilting the nose slightly forward should stop the plane from spinning). Torque rolling on the other hand would be the same as hovering except your keeping the plane perfectly vertical to allow the engines TORQUE to spin the plane around it's axis.
Most people can torque roll well enough but as i mentioned earlier, I have'nt seen anyone hover.
If there is someone out there who can , Please Record and Post it for all to see. Good Luck
