I've been watching the screenshots forum and have noticed a lot of areobatic challenges going on. So I present you the the ultimate areobatic challenge, the "Torque Roll". This is one of the most difficult areobatic manouvers I have ever witnessed and have actually only seen R/C aircraft (Due to high Power to Weight Ratio) acomplish it.  Here's how it goes. Take the aircraft into a 90 degree vertical climb. Reduce power until Rate of Climb is zero and maintain zero. Adjust yaw and attitude to keep it vertical and slowly roll the aircraft around its Y-Axis while litterally hanging on the prop. Throttle up and take her out.
I've tried this in FS2002 but the aircraft either is too heavy one I loose control.
